Furthermore, the first fixture body  101  includes a front portion  106  and a rear portion  107 , with the lateral arms  108   a,    108   b  extending from the front portion  106  of the body  101  on opposite sides thereof. The lateral arms  108   a,    108   b  illustratively define a frontal opening  105  therebetween shaped and sized to receive a portion of the accessory therein (e.g., the first portion of the accessory  70 ). 
     In some embodiments, the first fixture  100  can be substantially planar such that the bottom surface  102  can lay flat on the vehicle surface  63 . In alternative embodiments, the first fixture body  101  can be at least partially curved (e.g., along the bottom surface) to cooperate with a curved surface of the vehicle  60 , for example. In addition, when the first fixture  100  is connected to the vehicle surface  63 , the first fixture body  101  can be disposed in a manner where the lateral arms,  108   a,    108   b  extend away from the vehicle  60  (e.g., away from the second fixture  200 —see  FIGS.  3 A and  3 B ). Therefore, it is appreciated that the frontal opening  105  is defined in a manner such that it opens towards the exterior of the vehicle  60 . However, it is appreciated that the first fixture  100  can be connected to the vehicle  60  in any suitable manner, such as the lateral arms  108   a,    108   b  extend inwardly, i.e., towards the second fixture  200 , for example. 
     In some embodiments, the first fixture  100  can include a locking assembly  120  operatively connected to the first fixture body  101 , and operable to selectively secure an accessory portion within the frontal opening  105 . More specifically, and as will be described further below, the locking assembly  120  can include one or more elongated members connected to the lateral arms of the body. The elongated members can be adapted to extend between the lateral arms  108   a,    108   b,  thereby closing the frontal opening  105 . In some embodiments, the locking assembly  120  can be operable between an open configuration, where access is provided to the frontal opening  105  for positioning the accessory portion therein, a closed configuration, where the frontal opening  105  is at least partially closed and where the accessory portion is generally confined within the frontal opening  105 , and a locked configuration, where the accessory portion is secured within the frontal opening  105 . 
     Now referring to  FIGS.  8  to  10   , the second fixture  200  includes a second fixture body  201  removably connectable to the vehicle surface via any suitable manner, such as via fasteners  170 , for example. In this embodiment, the second fixture body  201  can be generally li-shaped and include lateral segments  208   a,    208   b  extending on opposite sides of the body  201 . More specifically, the second fixture body  201  can include a bottom portion (e.g., bottom surface  202 ), a top portion (e.g., top surface  203 ) opposite the bottom portion, and sidewalls  204  extending between the bottom and top surfaces  202 ,  203 . Furthermore, the second fixture body  201  includes a front portion  206  and a rear portion  207 , with the lateral segments  208   a,    208   b  extending from the bottom surface  202  of the body  201  on opposite sides thereof. As such, it should be understood that the lateral segments  208   a,    208   b  extend generally perpendicularly with respect to the second fixture body  201  and are adapted to engage the surface of the vehicle to connect the second fixture  200  to the vehicle. The lateral segments  208   a,    208   b  illustratively define a passage  205  therebetween shaped and sized to receive a portion of the accessory therein (e.g., the second portion of the accessory  70 ). 
     As seen in  FIG.  10   , in some embodiments, the passage  205  extends through the second fixture body  201 , i.e., extends between the front and rear portions  206 ,  207 . In this embodiment, the passage  205  is inwardly tapered between the front and rear portions such that the distance between the lateral segments  208   a,    208   b  proximate the front portion  206  is greater than the distance between the lateral segments  208   a,    208   b  proximate the rear portion  207 , although other configurations are possible and may be used. Furthermore, when connecting the second fixture  200  to the vehicle, the lateral segments  208   a,    208   b  engage the vehicle surface such that the vehicle surface further defines the passage  205 . In other words, the passage  205  can be defined between the lateral segments  208   a,    208   b,  and between the bottom surface  202  and the vehicle surface. However, it is appreciated that other configurations of the second fixture  200  are possible, such as having a passage  205  which extends only partially through the second fixture body  201 , for example. It is appreciated that securing the accessory to at least one of the first and second fixtures  100 ,  200  can secure the accessory to the vehicle, such that the accessory will remain connected thereto during use of the vehicle (e.g., while driving/travelling). 
     Referring back to  FIGS.  1  to  3 B , a possible embodiment of the accessory  70  will be described. It should be understood that the following description of the accessory second directions can be generally the same such that the first protruding portion  77  extends in the same direction as the second protruding portion  78 . For example, the first protruding portion  77  can extend towards the second end  73 , and thus towards the second protruding portion  78 , and the second protruding portion  78  can extend away from the second end  73 , and thus away from the first protruding portion  77 . In this embodiment, and as seen in  FIG.  2   , the first direction  81  is generally perpendicular to the second direction  82 , where the first protruding portion  77  extends downwardly from the first end  72  so as to enable engagement with the frontal opening from above, and the second protruding portion  78  extends away from the second end  73  so as to enable engagement with the passage from the front. However, and as will be described further below, the first protruding portion  77  can include transversely extending protrusions for engaging the first fixture. As such, it is appreciated that the transversely extending protrusions can be substantially parallel to the second direction  82 . 
     In addition, the first and second protruding portions  77 ,  78  can be separated from one another by a gap  79  (see  FIG.  1   ), which can be substantially equal to the gap  11  of the accessory mounting system  10  (see  FIG.  3 A ). Therefore, it should be understood that, in this embodiment, the first and second protruding portions  77 ,  78  are spaced from one another by generally the same distance separating the first and second fixtures  100 ,  200 . 
     In some embodiments, the first fixture  100  and second fixture  200  can be substantially aligned across the surface of the vehicle  63 , as shown in  FIG.  3 A . In other embodiments, the first and second fixtures  100 ,  200  can be at least partially offset from one another, but remain parallel such that the first and second directions  81 ,  82  also remain parallel, as shown in  FIG.  3 B . In some embodiments, the protruding portions  77 ,  78  are integrally formed as part of the accessory  70 , although it is appreciated that at least one of the protruding portions  77 ,  78  can be removably connectable to the accessory  70 , and thus interchangeable with other designs of protruding portions, for example. 
     In some embodiments, the first fixture body  101  can include a slot  115  (see  FIG.  11   ) defined in the bottom surface  102  and communicating with the frontal opening  105 . The slot  115  is shaped and sized to receive therein a part of the first protruding portion  77 , such as a distal end  77   a  (see  FIG.  17 C ) of the first protruding portion  77 , for example. In other words, the distal end  77   a  of the first protruding portion  77  can be adapted to extend within the slot  115  so as to be positioned below the first fixture body  101 , e.g., between the vehicle surface  63  and the bottom surface  102 . It is thus noted that the distal end  77   a  can extend substantially parallel to the second direction  82  (seen in  FIG.  2   ). As will be further described below, positioning the first protruding portion  77  within the slot  115  can prevent vertical movement of the accessory  70  (e.g., due to the abutment of the first protruding portion  77  with the first fixture body  101 ). Moreover, operating the locking assembly  120  in the locked configuration can prevent horizontal movement of the accessory  70 , or at least of the first protruding portion  77 . Finally, it is noted that engagement of the accessory  70  with fixtures positioned at least two (2) separate locations can prevent rotation of the accessory  70  on the vehicle surface  63 , thereby blocking movement and securing the accessory  70 . 
     In some embodiments, the accessory  70  can be adapted to fit within the gap  11 , which can be different for each vehicle  60 , without requiring adjustment(s). In other embodiments, the accessory  70  can be configurable between different configurations, such that the gap  79  between the protruding portions  77 ,  78  can be adjusted to match the gap  11  of the vehicle surface  63 . For example, multiple hole patterns, slots and/or interface plate(s) can be used to adjust the size of the gap  79 . Alternatively, or additionally, the accessory mounting system  10  can be configurable between different configurations such that the gap  11  can be adjusted to match the gap  79 , for example. 
     Now referring to  FIGS.  11  to  13   , in addition to  FIGS.  4  to  7   , as mentioned above, the locking assembly  120  can be selectively operated to secure the accessory  70  to at least one of the first and second fixtures  100 ,  200 , such that the accessory  70  is secured to the vehicle  60 . In this embodiment, the locking assembly  120  includes a first lock member  130  and a second lock member  140  adapted to cooperate with one another to prevent inadvertent release of the accessory  70  from within the frontal opening  105  of the first fixture body  101 . In other words, in this embodiment, the first and second lock members  130 ,  140  cooperate together to selectively close the frontal opening  105 , thereby securing the accessory portion therein. 
     In some embodiments, the first and second lock members  130 ,  140  include complementary locking features configured to engage one another when operating the lock assembly  120  in the closed configuration. More specifically, and as will be described further below, the first lock member  130  can include a first hinged member  132  pivotally connected to the body  101  and movable between a closed position (see in  FIGS.  12  and  13   ) where the first hinged member  132  extends at least partially across the frontal opening  105 , and an open position (seen in  FIG.  11   ). Similarly, the second lock member  140  can include a second hinged member  142  pivotally connected to the body  101  and movable between a closed position (seen in  FIGS.  6  and  13   ) where the second hinged member  142  extends at least partially across the frontal opening  105 , and an open position (seen in  FIGS.  11  and  12   ). It should be noted that positioning the hinged members  132 ,  142  in the closed position generally corresponds to operating the locking assembly  120  in at least one of the closed configurations and the locked configuration. 
     As seen in  FIGS.  7  and  11  to  13   , the first hinged member  130  can be pivotally connected to the first fixture body  101 , and more specifically to one of the lateral arms, such as the first lateral arm  108   a.  In this embodiment, the first hinged member  132  is generally elongated and includes a proximal end  132   a  pivotally connected to the lateral arm  108   a  and a distal end  132   b  opposite the proximal end  132   a.  The first hinged member  132  can be operated between the open position ( FIG.  11   ), where the distal end  132   b  is spaced from the fixture body  101 , and the closed position ( FIG.  12   ), where the distal end  132   a  is positioned proximate the fixture body  101 . In the illustrated embodiment, the distal end  132   b  of the first hinged member  132  is adapted to engage (e.g., abut against) the second lateral arm  108   b  when in the closed position such that the first hinged member  132  extends across and closes the frontal opening  105 , as seen in  FIG.  12   . It should thus be understood that, when the first protruding portion  77  of the accessory  70  is positioned within the frontal opening  105 , closing the first hinged member  132  encloses the accessory portion  700  within the frontal opening  105 . 
     In the present embodiment, the first hinged member  132  has a generally arcuate shape adapted to surround the accessory portion  77  positioned within the frontal opening  105 . Moreover, in some embodiments, the first hinged member  132  can be provided with a secondary slot  135  (seen in  FIG.  7   ) shaped and sized to receive therein a part of the first protruding portion  77 , such as a proximal end  77 b of the first protruding portion  77 , for example. In other words, the proximal end  77 b of the first protruding portion  77  can be adapted to extend within the secondary slot  135  so as to be positioned below the first fixture body  101 , e.g., between the vehicle surface  63  and the first hinged member  132 . It is noted that the proximal end  77 b can extend substantially parallel to the second direction  82  (seen in  FIG.  2   ) and opposite to the distal end  77   a, although other embodiments are possible.    
     Still referring to  FIGS.  7  and  11  to  13   , the second hinged member  140  can be pivotally connected to the first fixture body  101 , and more specifically to one of the lateral arms, such as the second lateral arm  108   b.  In this embodiment, the second hinged member  142  is generally elongated and includes a proximal end  142   a  pivotally connected to the second lateral arm  108   b  and a distal end  142   b  opposite the proximal end  142   a.  The second hinged member  142  can be operated between the open position ( FIGS.  11  and  12   ), where the distal end  142   b  is spaced from the fixture body  101 , and the closed position ( FIGS.  6  and  13   ), where the distal end  142   a  is positioned proximate at least one of the fixture body  101  and the first hinged member  132 . In the illustrated embodiment, the distal end  142   b  of the second hinged member  142  is adapted to engage (e.g., abut against) the first hinged member  132  when in the closed position such that the first and second hinged members  132 ,  142  at least partially overlap one another across the frontal opening  105 . In the present embodiment, the second hinged member  142  has a generally arcuate shape complementary with respect to at least a portion of the first hinged member  132  so as to conform therewith and facilitate engagement of the first and second hinged members  132 ,  142  with one another. 
     It should be noted that the locking assembly  120  is said to be in the closed configuration when the first and second hinged members  132 ,  142  are closed (i.e., pivoted inwardly, thereby closing the frontal opening  105  and forming a loop  1000  (see  FIG.  6   ) surrounding at least a portion of the accessory), as seen in  FIGS.  6  and  13   . The locking assembly  120  is said to be in the open configuration when the first and second hinged members  132 ,  142  are open (i.e., pivoted outwardly, thus breaking the loop  1000  and providing access to the frontal opening  105 ), as seen on  FIG.  11   . 
     As seen in  FIG.  7   , the first hinged member  132  can be connected to the first lateral arm  108   a  via a first pivot pin  113 , and the second hinged member  142  can be connected to the second lateral arm  108   b  via a second pivot pin  123 . The first and second pivot pins  113 ,  123  respectively define pivot axes  114 ,  124  around which the first and second hinged members  132 ,  142  can rotate during operation of the locking assembly  120 . In this embodiment, the first and second pivot pins  113 ,  123  are provided with respective retaining rings  119  configured to prevent the pivot pins from disengaging the first fixture body  101  and the hinged members  132 ,  142 , thereby maintaining the hinged members  132 ,  142  pivotally connected to the fixture body  101 , although other configurations are possible. 
     As previously explained, in this embodiment, the second hinged member  142  is adapted to engage an outer surface of the first hinged member  132 . In other words, closing the locking assembly  120  can include initially closing the first hinged member  132  before the second hinged member, with second hinged member  142  being configured to at least partially cover the first hinged member  132 . In addition, in some embodiments, the first hinged member  132  includes a first locking aperture  134 , and the second hinged member  142  includes a second locking aperture  144  configured to align with the first locking aperture  134  when the locking assembly  120  is in the closed configuration. As such, a locking device, such as a padlock  180  (seen in  FIG.  17 H ) can be inserted through the locking apertures  134 ,  144  and locked, thereby operating the locking assembly  120  in the locked configuration and preventing the first and second hinged members  132 ,  142  from being moved in the open position. 
     As seen in  FIG.  6   , the locking apertures  134 ,  144  can be adapted to be aligned with one another approximately halfway across the frontal opening  105  to facilitate insertion of the locking device. However, it is appreciated that the locking apertures  134 ,  144  can be positioned at any suitable location along the hinged members  132 ,  142  to align with one another and enable the use of a padlock to effectively lock the hinged members  132 ,  142  in the closed position. It should be appreciated that operating the locking assembly  120  in the locked configuration can prevent theft of the accessory  70  mounted to the accessory mounting system  10 . 
     With reference to  FIGS.  7  and  11  to  13   , the locking assembly  120  can include a resilient member  150  removably coupled to the second hinged member  142  and configured to bias the locking assembly  120  in the closed configuration. As seen in  FIG.  7   , the resilient member  150  can be removably coupled to the second hinged member  142  via a resilient member fastener  151 , although other methods of connections are possible, such as via a slot and key connection, snap connection, press-fit connection, or any other suitable method. It is noted that moving the second hinged member  142  between the open and closed positions correspondingly moves the resilient member  150 , i.e., the second hinged member  142  and the resilient member pivot  150  about the second pivot axes  124 . In some embodiments, the resilient member  150  is selectively connectable to the first hinged member  132  in a manner such that at least one of the first and second hinged members  132 ,  142  is biased in the closed position. In the present embodiment, connecting the resilient member  150  to the first hinged member  132  biases each one of the first and second hinged members  132 ,  142  in the closed position, thereby further securing the accessory portion within the frontal opening  105 . 
     In some embodiments, the first hinged member  132  can include a tab  138  extending outwardly therefrom, and the resilient member  150  can include a tab receiving opening  158  adapted to have the tab  138  extend therethrough. As seen in  FIGS.  11  to  13   , the tab  138  can be generally hook-shaped such that insertion of the tab  138  through the tab-receiving opening  158  can prevent the resilient member  150  from disengaging the first hinged member  132 . More particularly, in this embodiment, the resilient member  150  includes a rubber strap configured to be deformed, e.g., stretched, to enable the tab receiving opening  158  to reach the tab  138 , and allow the tab  138  to extend through the opening. Once the resilient member  150  is released (e.g., no longer stretched) the tab  138  abuts a side of the tab-receiving opening  158 , with the hook-shape thereof preventing the resilient member  150  from disengaging the first hinged member  132 . As such, it is noted that, in order to remove the tab  138  from within the tab-receiving opening  158 , it can be required to stretch the resilient member  150  once again to unhook the resilient member  150  from the first hinged member  132 . In this embodiment, the tab  138  is positioned proximate the proximal end  132   a  of the first hinged member  132 , and the tab-receiving opening  158  is positioned near the distal end of the resilient member  150 . However, it is appreciated that other configurations are possible, such as having the tab  138  be positioned on the second hinged member and have the tab-receiving opening  158  positioned on the first hinged member, for example. 
     The resilient member  150  is typically used as an additional and/or alternative feature to prevent inadvertent opening of the hinged members  132 ,  142 . More particularly, in some embodiments, and with reference to  FIGS.  14  to  14 B , the locking assembly  120  can be further provided with a complementary locking feature  160  adapted to prevent accidental (i.e., undesired) release of the accessory. In some embodiments, the complementary locking feature  160  can include complementarily shaped components provided on the first and second hinged members  132 ,  142  and configured to engage one another in a manner such that opening the first hinged member  132  (from the closed configuration) is at least partially prevented. Therefore, it is noted that, if the accessory portion within the frontal opening  105  creates a force on the first hinged member  132  (i.e., from within the frontal opening  105 ), the complementary locking feature  160  would generally prevent the first and second hinged members  132 ,  142  from opening (e.g., even in the absence of the resilient member  150 ). 
     In the present embodiment, the complementarily shaped components include a first component, such as a recess  162  provided proximate the distal end  132   b  of the first hinged member  132 , and a second component, such as a protrusion  164  provided proximate the proximal end  142   a  of the second hinged member  142 . In some embodiments, the recess  162  is provided on an outwardly facing side of the first hinged member  132 , and the protrusion  164  is provided on an inwardly facing side of the second hinged member  142 . Therefore, it is appreciated that closing the hinged members  132 ,  142  snugly positions the protrusion  164  within the complementarily shaped recess  162 . 
     Referring to  FIGS.  15  and  16   , in addition to  FIGS.  14  to  14 B , the recess  162  and the protrusion  164  each include a corresponding locking surface  163 ,  165 . As seen in  FIG.  16   , the locking surfaces  163 ,  165  can be tangent to an imaginary circle centered at the second pivot axis  124  such that, when the locking assembly  120  is in the closed configuration, the locking surfaces  163 ,  165  have their normal vectors  163 a,  165 a substantially aligned with a perpendicular projection  166  of the second pivot axis  124 . Therefore, it is noted that attempting to open the first hinged member  132 , when in the closed configuration, causes the locking surface of the recess  163  to push against the locking surface of the protrusion  165 , thereby creating an outwardly oriented axial force. Moreover, due to the alignment of the normal vectors  163 a,  165 a with the second pivot axis projection  166 , the axial force does not create a rotational force about the second pivot axis  124 , and thereby does not engage the second hinged member  142  in rotation. In other words, when in the closed configuration, the complementary locking feature  160  prevents the hinged members  132 ,  142  from opening due to an outwardly oriented force being applied on an inner surface of the first hinged member  132 . It should thus be understood that, in this embodiment, the second hinged member  142  is required to be opened to enable opening the first hinged member  132 . However, it is appreciated that other configurations are possible. 
     As an example, and with reference to  FIG.  16   , when an opening force  1100  is applied to the first hinged member  132 , the pivotal connection of said hinged member  132  induces a rotational force  1400  about the first pivot axis  114 . The rotational force  1400  causes the locking surface of the recess  163  to push against the locking surface of the protrusion  165  and creates an axial force on the locking surface of the protrusion  165 . As explained above, the protrusion locking surface  165  is configured to have its normal vector  165 a substantially in line with the perpendicular projection  166  of the second pivot axis  124  (i.e., without creating a material lever arm relative to said second pivot axis  124 ), such that the axial force does not contribute to opening the second hinged member  142 . The axial force is instead divided into shear forces applied to the first and second pivot pins  113 ,  123 . A common example of this phenomenon can be described by trying to open a door by pushing directly on the pins of its hinges. It should thus be understood that, in the described embodiment, a rotational force (i.e., a force and a lever arm) is required in order to open the second hinged member  142 , which then enables the first hinged member  132  to be freely open. 
     As mentioned above, the complementary locking feature  160  is configured to neutralize, or at least partially counteract, an opening force applied to the first hinged member  132  toward its opening direction (as seen in  FIG.  16   ). However, the complementary locking feature  160  does not necessarily prevent other opening forces applied to said second hinged member  142  toward its opening direction from opening the locking assembly  120 . The previously described resilient member  150  thereby also contributes to maintaining the hinged members  132 ,  142  closed. 
     Now referring to  FIGS.  17 A to  17 H , and broadly referring to  FIGS.  1  to  16   , an exemplary method for mounting an accessory  70  to a vehicle surface  63  is shown and will now be described. The method  600  may be completely or partially implemented using the accessory mounting system  10  and, as such, will be described with reference to the accessory mounting system  10  described herein. 
     The method can start by determining which of the vehicle surface  63  and the accessory  70  will define the distance between the first and second fixtures  100 ,  200  (i.e., gap  11 ) and/or the distance between the protruding portions of the accessory (i.e. gap  79 ), as seen in  FIGS.  17 A and  17 B . For example, if the width of the accessory  70  is greater than the width of the vehicle surface  63 , the distance between the fixtures  100 ,  200  cannot be equal to the width of the accessory  70 . Thereby, the distance between the protruding portions  77 ,  78  is adjusted to the size of the gap  11  between the first and second fixtures  100 ,  200 . 
     Then, at  FIG.  17 B , the method includes the step of installing the accessory mounting system  10  to the vehicle  60 , by connecting the first fixture  100  and the second fixture  200  to the vehicle surface  63 , thereby defining the gap  11  therebetween. At this step, the locking assembly  120  is preferably in the open configuration for exposing the frontal opening  105 . Then, as seen in  FIGS.  17 C and  17 D , the first protruding portion  77  is oriented towards the opened locking assembly  120  of the first fixture  100  (i.e., towards the frontal opening  105 ), and the second protruding portion  78  is oriented towards the passage  205  of the second fixture  200 . The accessory  70  is then lowered towards the vehicle surface  63  for engaging the first protruding portion  77  in the frontal opening  105  of the first fixture  100  and engaging the second protruding portion  78  in the passage of the second fixture  200 . This can be accomplished by performing a translation of the second protruding portion  78  toward the second fixture  200  and lowering the first protruding portion  77  within the frontal opening  105 . However, it is appreciated that other methods or steps are possible and may be used for connecting the accessory  70  to the mounting system  10 , and thus to the vehicle  60 . 
     At this point, the first protruding portion  77  and the second protruding portion  78  should be engaged with corresponding fixtures  100 ,  200 , as shown in  FIGS.  17 Eand  17 F . 
     The locking assembly  120  can then be operated in the closed configuration, as seen in  FIGS.  17 G and  17 H . In this embodiment, this step includes:  1 ) closing the first hinged member  132  until the distal end thereof abuts the body  101  of the first fixture  100  ( FIG.  17 G );  2 ) closing the second hinged member  142  for covering at least a portion of the first hinged member  132 , and until the distal end of the second hinged member  142  abuts the first hinged member  132  ( FIG.  17 H ), and  3 ) securing the resilient member  150  to the first hinged member  132  ( FIG.  17 H ). 
     As seen in  FIG.  17 H , the method can include locking the locking assembly  120  via a locking device  180  (e.g., a padlock) installed through the corresponding apertures  134 ,  144  of the hinged members  132 ,  142 , respectively. 
     It should be understood that a method for releasing the accessory  70  from the accessory mounting system  10  substantially includes the steps of the method described above but performed in reverse order. 
     It will be understood that implementations of the accessory mounting system  10  described herein can be used in relation with various vehicles, and for various accessories, such as fuel tanks, bags, racks, etc. It is also noted that the mounting system  10  can facilitate attaching and disconnecting (i.e., detaching) accessories to and from a vehicle, thereby enabling easy and safe transport and use of these accessories at a desired location. 
     Alternate embodiments are shown in  FIGS.  18  to  20   , whereby the frontal opening  105  of the first fixture  100  defines a D-shaped opening when the locking assembly  120  is in the closed configuration (best seen in  FIG.  20   ), rather than a generally hexagonal-shaped opening, such as in the previously described embodiments (e.g., seen in  FIG.  6   ). Moreover, the mounting system  10  can include a mounting plate  190  adapted to be connected between the vehicle surface and the first fixture body  101 . The mounting plate  190  can be configured to prevent, or at least reduce, wearing down of the mounting system and related components. For example, the mounting plate  190  can reduce wear on the accessory (e.g., the first end and/or the first protruding portion), the mounting system (e.g., the first fixture body) and/or the vehicle surface. As such, in this embodiment, the mounting plate  190  is configured to allow secure installation of the fixture body  101  and reduce the risks of plastic deformations, creeping, cracking, shrinking, etc. 
     In addition, the mounting plate  190  can be adapted to provide a secure connection for the fixture body in embodiments where the bearing surface of the fixture (e.g., the vehicle surface) is covered by a film or layer of protective material, for example. In some embodiments, the mounting plate  190  can be made of a softer material relative to the material of the fixture body  101 . For example, the material of the mounting plate  190  can be a plastic. 
     The mounting plate  190  can be connected to the vehicle surface and/or the mounting fixture (i.e., on the bottom surface thereof) via any suitable method, such as via adhesion (e.g., using a glue), via fasteners or via a combination thereof. In some embodiments, the mounting plate  190  can be a sticker positioned between the fixture body and the vehicle surface. As seen in  FIG.  18   , the mounting plate  190  can have a generally M-shape, with a central portion thereof adapted to generally conform to the shape of the first fixture  100  (e.g., the Li-shaped first fixture  100 ). However, it is appreciated that the mounting plate  190  can have any other suitable shape and configuration. 
     It should be noted that the mounting plate  190  described above in relation with the first fixture  100  can alternatively, or additionally, be provided for the second mounting fixture, such as the second fixture shown in  FIG.  8   , for example. In other words, each of the first and second fixtures can be provided with their respective mounting plates for providing substantially the same advantages for both fixtures (e.g., reduced wear, increase lifespan, reduce the risks of plastic deformations, creeping, cracking, shrinking, etc.). 
     It should be noted that the above-described mounting system may be embodied in other specific forms. The described example implementations are to be considered in all respects as being only illustrative and not restrictive. For example, in the embodiments described herein, the mounting system includes a pair of fixtures, and includes a first fixture and a second fixture installed opposite one another. However, it is noted that, in some embodiments, the mounting system can include a pair of fixtures which includes two (2) of the same type of fixtures, such as a pair of first fixtures, for example, or a single fixture, whereby the first fixture is the only fixture holding the accessory connected to the vehicle. In other alternative embodiments, the first and second fixtures can be provided with the protruding portions, and the accessory itself is provided with openings, passages and/or locking assemblies configured for securing the accessory to the fixtures. In some embodiments, the first and/or second fixtures are typically made of a polymeric material (e.g., plastic), which can be moulded and/or 3D printed, for example. However, it is appreciated that the first fixture can be made of any other suitable material, such as a metallic material or a composite material, for example. 
     Additionally, and as previously described, it is noted that the mounting fixtures are adapted to be connected to the vehicle using fasteners, such as screws. The vehicle can be provided with pre-drilled holes configured to have components similar to the mounting fixtures be connected thereto at predetermined locations. It is possible to create (e.g., drill) additional holes in the vehicle surface to enable connection of the mounting fixture at different locations on the vehicle or enable connection of more mounting fixtures. In some embodiments, the mounting fixtures can be movably connected to the vehicle, and selectively secured in the desired location. As such, the position of the accessory on the vehicle can be adjusted. For example, the mounting system includes a rail assembly comprising a pair of rails connected to the vehicle surface, with one or more of the mounting fixtures connected to the rails. The mounting fixtures are slidably mounted to the rails to adjust their position there along, and thus upon the vehicle. The mounting fixtures can further be selectively secured to the rails, thereby securing the accessory at a desired location and/or configuration on the vehicle. It is thus noted that the accessory can be mounted to a desired portion of the vehicle located along the rails and/or that multiple accessories can be mounted to the vehicle along the pair of rails. As will be described further below, the rail assembly can be connected to the vehicle in a spaced apart relation such that a pair of mounting fixtures can be mounted to respective rails opposite one another. 
     Referring to  FIGS.  21  to  22     b , the mounting system  10  can include a pair of mounting assemblies  300  removably connectable to the vehicle surface  63 . In the illustrated embodiment, the mounting system  10  includes a first mounting assembly  302  and a second mounting assembly  304  adapted to be removably connected to the vehicle surface opposite one another along the vehicle surface  63 . Each mounting assembly  300  can include an elongated rail  320  and one or more mounting fixtures, such as the previously described first and second mounting fixtures  100 ,  200 , adapted to be slidably connected to the rail  320 . The rails  320  are illustratively mounted parallel to one another and separated by the gap  11 , which can correspond to a width of the vehicle surface  63 , for example. Therefore, the first mounting fixture  100  can be generally positioned opposite the second mounting fixture  200  (e.g., on an opposite side of the vehicle surface  63  and across the gap  11 ), as seen in  FIG.  21   . However, it is appreciated that the rails  320  can be mounted to the vehicle in any suitable manner, such as at an angle relative to one another, perpendicular to one another, axially aligned with one another, etc. 
     In some embodiments, each rail  320  can be provided with a plurality of mounting fixtures positioned at any suitable location along the rail  320 , thereby allowing the accessory to be further secured to the vehicle and/or allowing for additional accessories to be connected to the vehicle. 
     Now referring to  FIGS.  23  to  27   , in addition to  FIGS.  21  to  22     b , the rail  320  of a given mounting assembly  300  is generally elongated and has a thickness extending between a top surface  322  and a bottom surface  324 . In this embodiment, the bottom surface  324  is adapted to engage (e.g., contact) the vehicle surface  63  to enable connection of the rail  320  to the vehicle. In addition, the elongated rail  320  includes an inner section  325  defining an inner edge  326 , and an outer section  327  defining an outer edge  328 . It is noted that, in this embodiment, the inner edge  326  corresponds to the edge of the rail  320  facing the mounting assembly  300  installed on the other side of the vehicle surface  63 , and that the outer edge  328  of the rail  320  corresponds to the edge facing away from the vehicle. 
     In the present embodiment, the rail  320  includes a slot  330  extending along a length of the rail  320 . In this embodiment, the slot  330  extends longitudinally along the rail, and more particularly along an entire length thereof. As seen in  FIGS.  22   a ,  22   b    and  23 , the slot  330  opens at both ends of the rail  320 , although it is appreciated that other configurations are possible, such as having the slot  330  open at a single end of the rail  320 , or having the slot  330  extend perpendicularly relative to the length of the rail  320  at one or more locations, for example. Moreover, the slot  330  illustratively includes an opening  332  defined on the top surface  322  of the rail  320  to enable components positioned within the slot  330  to be accessible and/or to extend out of the slot  330  through the opening  332  in the top surface  322 . As seen in  FIGS.  23  and  24   , the rail  320  can be connected to the vehicle via fasteners  172  (e.g., nut and screw assemblies) extending through a thickness of the rail  320  and into the vehicle. In this embodiment, the fasteners  172  are positioned along the slot  330  and are provided with generally flat heads  17   4  so as to be generally coplanar with the slot  330 , although other configurations and/or positions of the fasteners  172  are possible and may be used to connect the rail  320  to the vehicle. 
     In some embodiments, the rail  320  can be provided with a plurality of fastener apertures  176  spaced along the length of the rail  320  (e.g., along the slot  330 ). As such, the rail  320  can be connected to any given vehicle surface provided with predrilled holes configured to have components fastened thereto. It is thus appreciated that the rail  320  can be adapted to be connected to any type of vehicle provided with any standard fastening holes, for example. In some embodiments, additional holes can be drilled into the vehicle surface to enable the use of additional fasteners  172  and provide a more secure connection of the rail  320  to the vehicle. It should be noted that, in some embodiments, the rail  320  can be secured via one, two, three or any other suitable number of fasteners (e.g., nut and screw assemblies). 
     Referring more specifically to  FIGS.  25  to  27   , the mounting assembly  300  further includes a connector  350  configured to engage the slot  320  and be displaced along its length. The connector  350  can be further adapted to have the mounting fixture (e.g., the first or second mounting fixture  100 ,  200 ) be connected thereto in order to couple the mounting fixture to the rail  320 . The connector  350  can be shaped and sized to be slidably mounted within the slot  330  and can be inserted within the slot  330  via one of the openings at either end of the rail  320 . It is noted that having the connector  350  slidably mounted within the slot  330  enables the connected mounting fixture to slide along the rail  320  (i.e., due to its connection to the connector  350 ). In the present embodiment, the connector  350  includes a head portion  352  shaped and configured to fit within the slot  330 , and a shank portion  354  extending from the head portion  352  and adapted to extend through the opening  332  of the slot  330 . As will be further described, the shank portion  354  extends upwardly from the rail  320  to enable connection with the mounting fixture. 
     In this embodiment, the slot  330  and the connector  350  can be at least partially complementarily shaped so as to enable movement of the connector  350  along the slot  330  (i.e., along the length of the rail  320 ) while preventing other types of movements. For example, in some embodiments, the slot  330  can have a generally inverted T-shape, where the top surface  322  overhangs a portion of the slot  330  on either side thereof for defining the opening  332 . In other words, the opening  332  of the slot  330  is narrower than a main portion  334  thereof. The head portion  352  of the connector  350  can be complementarily shaped with respect to the main portion  334  of the slot  330 , and the shank portion  354  can be shaped and adapted to extend through the opening  332 . Moreover, and as seen in  FIGS.  25  and  26   , the head portion  352  is adapted to prevent removal of the connector  350  from the slot  330  through the opening  332  by abutting against the top surface  322  which overhangs the slot  330 . In some embodiments, the connector  350  and the slot  330  form a dovetail connection, or any other similar connection, which enables axial movement of the connector along the slot  330 , while preventing radial movement. 
     Still referring to  FIGS.  23  to  27   , the main portion  334  of the slot  330  can include sidewalls  336  extending parallel to one another on opposite sides of the slot  330 . As previously described, the head portion  352  of the connector  350  is adapted to fit into the main portion  334  and is slidably mounted therein. Moreover, the head portion  352  can include one or more lateral edges  355  configured to prevent rotation of the head portion  352  when positioned within the slot  330 . For example, in this embodiment, the head portion  352  has a hexagonal shape, and thereby includes three (3) pairs of parallel edges  355 . It should thus be understood that engaging the head portion  352  within the slot  330  correspondingly positions at least one pair of edges  355  in a face-to-face configuration with the sidewalls  336 . It is noted that the pair of lateral edges  355  engaging the sidewalls  336  of the slot  330  prevents rotation of the connector  350  within the slot  330 . 
     In this embodiment, and as seen in  FIGS.  25  and  26   , the shank portion  354  is adapted to extend through the opening  332  to enable the mounting fixture  100  to be coupled to the shank portion  354 . In some embodiments, the mounting fixture  100  can be provided with one of a female connection and a male connection, and the shank portion  354  can be provided with the other one of the female connection and the male connection configured to engage one another. More specifically, in this embodiment, the shank portion  354  is provided with the female connection, such as a borehole  356 , and the mounting fixture  100  includes the male connection, such as mounting fasteners  170  adapted to extend through the first mounting fixture  100  (seen in  FIG.  26   ), through the second mounting fixture  200  (seen in  FIG.  27   ) and into the corresponding borehole  356 . It is noted that fastening the mounting fixtures  100 ,  200  onto the shank portion  354  (via the mounting fasteners  170 ) secures the connector  350  in place within the slot  330 , thereby securing the mounting fixtures along the rail  320  and on the vehicle surface. In some embodiments, the borehole  356  of the shank portion  354  and the mounting fastener  170  are threaded. Therefore, it is noted that fastening the mounting fastener  170  in the borehole  356  causes the head portion  352  to abut against the top surface  322  of the rail  320  (i.e., from within the slot  330 ), thereby squeezing the top surface  322  between the head portion  352  and the mounting fixture, and securing the connector  350  and the mounting fixture along the rail  320 . 
     It should be understood that the first and/or second mounting fixtures  100 ,  200  can be slidably coupled to the rail  320  via the connector  350  when the mounting fastener  170  is not fully fastened. As such, the mounting fixtures can be displaced up and down the slot  330  to a desired location, and the mounting fasteners  170  can be fastened until the connection with the connector  350  tightens, thereby blocking movement and securing the mounting fixtures in place. It should thus be understood that the accessory, which is connected to the mounting fixture, can therefore be connected to the vehicle at any desired location along the rail  320 . 
     In some embodiments, each mounting fixture is coupled to the rail  320  via at least two (2) mounting fasteners  170  coupled to respective connectors  350 . In other words, the mounting assembly  300  can include two (2) connectors  350  for each mounting fixture, although it is appreciated that other configurations are possible. Furthermore, and with reference to  FIGS.  26  and  27   , the mounting assembly  300  can include the mounting plate  190  adapted to be connected between the rail  320  and the corresponding mounting fixture. The mounting plate  190  can be configured to prevent, or at least reduce, wearing down of the mounting assembly and related components. For example, the mounting plate  190  can reduce wear of the accessory coupled to the mounting fixtures, of the mounting fixture itself, of the rail  320  and/or of the vehicle surface. 
     In this embodiment, the mounting plate  190  is further adapted to facilitate connecting any given mounting fixture with the corresponding connectors  350 . For example, the mounting plate  190  can be provided with apertures  192  shaped and sized to receive the shank portion  354  of one of the connectors  350 . As seen in  FIG.  26   , the mounting plate  190  can include a pair of apertures  192  adapted to have the shank portions  354  of adjacent connectors  350  extend therethrough. As such, movement of the connectors  350  relative to one another is blocked (i.e., movement of one connector  350  causes displacement of the mounting plate  190 , and thus of the other one of the connectors  350 ), and the mounting fixture can be aligned with both connectors  350 . 
     In addition, the mounting plate  190  can be adapted to provide a secure connection for the fixture body in embodiments where the bearing surface of the fixture (e.g., the top surface of the rail  322 ) is covered by a film or layer of protective material, for example. In some embodiments, the mounting plate  190  can be made of a softer material relative to the material of the mounting fixture so as to reduce the risks of plastic deformations, creeping, cracking, shrinking, etc. For example, the material of the mounting plate  190  can be a plastic. The mounting plate  190  can be connected to the top surface  322  of the rail  320  and/or to the mounting fixture (i.e., on the bottom surface thereof) via any suitable method, such as via adhesion (e.g., using a glue), via fasteners or via a combination thereof. In some embodiments, the mounting plate  190  can be a sticker positioned between the fixture body and the rail  320 . 
     Referring back to  FIGS.  21  to  22     b , the first and second mounting assemblies  302 ,  304  are illustratively installed opposite one another across the surface  63  of the vehicle  60 . Each mounting assembly  300  being provided with respective mounting fixtures, such as one or more first and/or second mounting fixtures  100 ,  200 , so as to connect different portions of an accessory to the vehicle such that the accessory extends between the mounting assemblies  302 ,  304 . In this embodiment, the mounting system  10  enables an accessory to be connected to a pair of mounting fixtures provided on separate rails  320  (e.g., the first mounting fixture  100  and the second mounting fixture  200 ). However, it should be noted that a single rail  320  can be provided with one or more mounting fixtures, and that an accessory can be coupled to the single rail  320 , thereby connecting the accessory to the vehicle using a single mounting assembly  300 . It is also appreciated that providing multiple mounting fixtures to one or more mounting assemblies  300  can enable to connection of multiple accessories to the vehicle, using one or more rails  320 . 
     In some embodiments, the rails  320  are made of a metallic material, such as aluminium, although other materials, or combination thereof can be used, such as a plastic, for example. The rails  320  can further be provided with a surface treatment, such as an anodizing process, to reduce wear and increase lifespan. The rails  320  can be manufactured via an extrusion process, which can provide a generally constant cross-section to the rail  320  along its length (e.g., the cross section shown in  FIG.  24   ). However, it is noted that other manufacturing processes are possible, such as moulding (e.g., in the case of plastic rails) or a 3D-printing process, for example. 
     As seen in  FIG.  24   , the rail  320  can include additional features, such as a second slot  338  defined in the inner section  325  of the rail  320 , whereas the slot  330  is defined in the outer section  327 . The second slot  338  can extend along a portion of the rail  320 , or alternatively along the entire length thereof. The second slot  338  can be adapted to provide a balance to the rail  320  such that the inner section  325  is not overly weighted compared to the outer section  327 . It is noted that connecting the rail  320  to the vehicle surface can block access to the second slot  338 . As such, the second slot  338  can have any suitable shape and/or size. However, in this embodiment, the second slot  338  has a similar shape as the slot  330 , although inverted. In other words, the second slot  338  has a T-shape, with an opening  339  defined through the bottom surface  324  of the rail  320 , which can enable connection of the rail  320  to the vehicle upside down. In some embodiments, the rail  320  can be connected to a vehicle in a manner providing access to either one of the slot  330  and the second slot  338 , or both, such that additional connectors and mounting fixtures can be installed, and additional accessories can be connected to the vehicle. 
     Referring to  FIGS.  22  to  24   , the inner and/or outer edges  326 ,  328  of the rail  320  can be shaped and adapted to conform to the shape of the vehicle to which the rail  320  is connected. For example, in this embodiment, the inner edge  326  is tapered inwardly such that the top surface  322  extends further than the bottom surface  324 . This configuration can facilitate connection of the rail  320  onto a snowmobile tunnel having an embossed pattern, for example. Additionally, in this embodiment, the rail  320  can be at least partially bevelled at each end thereof, thus defining bevelled ends  329 . The bevels can be made at any suitable angle, and along across a portion of the end, or across an entire length thereof. It is noted that the rail  320  can be tapered, bevelled or otherwise shaped and configured in any suitable, desired and/or required manner to facilitate positioning of the rail  320  onto the vehicle surface. In some embodiments, the rails  320  can be shaped to conform to various components of the vehicle, such as lights, seats, etc. It should also be noted that shaping the rails  320  to conform to the vehicle (e.g., via tapers, bevels, chamfers, etc.) can reduce the materials used to manufacture the rails  320 , which can reduce the weight of the rails  320  and thereby reduce manufacturing and handling costs. 
     Alternatively, it is appreciated that the rail  320  can have a generally rectangular shape, with parallel sides and edges, and a sufficient thickness enabling the accessories connected to the rails to extend over any pattern or obstacles on the vehicle surface. 
     Referring broadly to  FIGS.  21  to  27   , it is appreciated that a method for connecting an accessory to a vehicle using the mounting system  10  described herein can include the steps of; connecting at least one rail  320  provided with a slot  330  to a vehicle surface  63 , slidably mounting a connector  350  within the slot  330 , coupling a mounting fixture ( 100  or  200 ) to the connector  350  and fastening the mounting fixture  630  to the connector  350  to secure the mounting fixture along the rail  320 , and connecting the accessory to the mounting fixture (e.g., via the locking assembly  200 ). The above-listed steps can be performed in any suitable order, for example, the accessory can be coupled to the mounting fixture prior to connecting the fixture to the connector. It is noted that, in some embodiments, in order to connect the rail  320  to the vehicle surface  63 , additional holes may need to be drilled into the vehicle surface  63  to enable connection of the rail  320 . In the illustrated embodiments, connecting the rail  320  to the vehicle surface  63  includes connecting a pair of rails  320  in space apart relation, and coupling one or more mounting fixtures to each rail  320 . 
     The described example implementations are to be considered in all respects as being only illustrative and not restrictive. For example, in the embodiments described herein, the mounting system includes a pair of mounting assemblies, and includes a first rail and a second rail installed opposite one another. However, it is noted that, in some embodiments, the mounting system can include a pair of rails adapted to be mounted in an end-to-end manner, with the rails being configured to clip, or otherwise connect, to one another to define a longer rail, for example. The rails used in the mounting assemblies can be of the same length, or of varying lengths. Alternatively, the mounting assembly can include rails configured to adjust their respective lengths to a desired length, such as via a telescopic portion installed along the rail. 
     In other alternative embodiments, the accessory can be coupled directly to the connectors  350 . For example, the accessory can be provided with a connection portion complementarily shaped relative to the shank portion of the connector such that the accessory can be connected to the connector without an intermediary component (e.g., the mounting fixture). In yet other embodiments, the shank portion of the connector can be adapted to form a quick release coupling with the component it is connected to (e.g., the mounting fixture or the accessory), thereby facilitating connection and disconnection of the accessory to and from the vehicle. 
     It should be noted that the mounting assemblies described above provide flexibility to a user, where the accessories can be connected at the desired locations on along the rails. However, the length of the rails  320  (or the width of the vehicle surface) can limit the number of possible locations where an accessory can be connected and/or limit the number of accessories connectable to the vehicle via the mounting system. In some embodiments, the mounting system can include a stacking assembly adapted to cooperate with one of the mounting assembly (e.g., the rails and the mounting fixtures), the accessory and the vehicle to enable accessories to be mounted to the vehicle in a stacked configuration. As such, additional accessories can be mounted on the vehicle, for example, when there is no space left to connect an accessory to the rails and/or the mounting fixtures connected to the vehicle surface. 
     In some embodiments, the stacking assembly of the mounting system includes a support structure configured to be coupled to the vehicle in a manner such that the support structure is generally elevated (i.e., above the vehicle surface) to allow a first accessory to be connected to the mounting system below the support structure (e.g., via a first set of mounting fixtures). The stacking assembly can further include one or more mounting fixtures secured to the support structure such that a second accessory can be secured to the support structure (e.g., via a second set of mounting fixtures), and therefore stacked on the first accessory. 
     Referring to  FIGS.  28  to  32   , a stacking assembly  400  according to an embodiment is shown. The stacking assembly  400  can include a support structure  410  adapted to be coupled to the vehicle  60  and enable accessories to be stacked on top of each other. The support structure  410  can be provided with one or more mounting fixtures, such as a first mounting fixture  100  and a second mounting fixture  200 , mounted at opposite ends of the support structure  410 . More particularly, one of the first and second mounting fixtures  100 ,  200  can be mounted at a first end  41  Oa, and the other one of the first and second mounting fixtures  100 ,  200  can be mounted at a second end  41  Ob, although other configurations are possible. 
     As such, it is appreciated that an accessory  70  (seen in  FIGS.  30  and  31   ) provided with first and second protruding portions  77 ,  78 , for example, can be coupled to the support structure  410  (i.e., the first and second protruding portions  77 ,  78  are connectable to the first and second mounting fixtures  100 ,  200 , respectively). In this embodiment, and as shown in  FIGS.  30  and  31   , the support structure  410  can be positioned atop the accessory  70 , which is adapted to be connected to the vehicle  60  via any apparatus or system. For example, the accessory  70  can be mounted to the vehicle via a pair of mounting fixtures  100 ,  200 , via a pair of rails  320  (see  FIG.  21   ) or a combination thereof. In some embodiments, and as will be further described below, the support structure  410  is connectable to the first accessory  70  (i.e., the accessory positioned below the support structure  410 ). In other embodiments, the support structure  410  can be adapted to be connected to the vehicle surface  63 , or a separate component connected to the vehicle surface (e.g., another mounting fixture and/or a rail assembly). 
     In the present embodiment, the support structure  410  includes a first support segment  412  and a second support segment  414  coupled to each other to define a length of the support structure  410 . The first and second support segments  412 ,  414  are generally elongated and adapted to interlock with one another along their longitudinal axis. In addition, the first and second support segments  412 ,  414  are adapted to be selectively secured to one another such that the support structure  410  has a desired length. It is thus noted that the support structure  410  can be at least partially telescopic, whereby the first and second support segments  412 ,  414  cooperate with each other to define the desired length of the support structure  410 . It is appreciated that selecting a desired length of the support structure  410  correspondingly defines the distance between the mounting fixtures  100 ,  200  connected to each end of the support structure  410 . A such, the distance between the mounting fixtures can be adjusted, for example, based on the accessory being connected thereto. 
     Referring more specifically to  FIG.  29   , the first support segment  412  include a fixture end  416  adapted to have one of the first and second mounting fixtures  100 ,  200  be connected thereto. The fixture end  416  can include a generally flat platform  417  configured to receive thereon the mounting fixture and/or the mounting plate  190 . The platform  417  includes one or more apertures to enable connection of the mounting fixtures via corresponding mounting fasteners  170 . However, in alternative embodiments, the mounting fixtures can form an integral part of the support structure  410 . Furthermore, the first support segment  412  includes an interlocking portion  418  extending from the fixture end  416  along the longitudinal axis (A 1 ) of the first support segment  412 . The interlocking portion  418  is adapted to engage the second support segment  414  in a manner enabling telescopic connection of the first and second support segments  412 ,  414  together. 
     In some embodiments, the second support segment  414  can have generally the same structure as the first support segment  412 . In the present embodiment, the second support segment  414  is exactly the same as the first support segment  412 . More specifically, the second support segment  414  includes a fixture end  416  adapted to have one of the first and second mounting fixtures  100 ,  200  be connected thereto, and an interlocking portion  418  extending from the fixture end  416  along the longitudinal axis (A 2 ) of the second support segment  414 . It is noted that the interlocking portions  418  are configured to interlock one another in a manner enabling a telescopic connection therebetween. In this embodiment, each interlocking portion  418  includes a pair of interlocking members  420  shaped and sized to engage the interlocking members  420  of the other one of the interlocking portions  418  when the first and second support segments  412 , 414  are aligned and positioned “face-to-face” (e.g., with the fixture ends  416  opposite one another at either ends of the formed support structure  410 ). 
     As seen in  FIG.  29   , each interlocking portion  418  includes a pair of interlocking members  420  positioned side-by-side, with one of the interlocking members  420  being vertically higher (or lower) than the other one of the interlocking members  420 . In the illustrated embodiment, the interlocking member positioned on a left side of the first support segment  412  (i.e., interlocking member  420   a ) is vertically lower than the interlocking member positioned on a right side of the first support segment  412  (i.e., interlocking member  420   b ). It should thus be understood that the interlocking members  420  of the second support segment  414  correspondingly include a vertically lower interlocking member  420   a,  and a vertically higher interlocking member  420   b.  As such, when the first and second support segments  412 ,  414  engage each other in a “face-to-face” configuration, the higher interlocking member  420   b  of one interlocking portion  418  extends over the lower interlocking member  420   a  of the other interlocking portion  418 , and vice versa, and as seen in  FIG.  28   . In other words, the interlocking members  420  of a given interlocking portion  418  are offset relative to one another and configured to engage another offset pair of interlocking members  420 . 
     It is noted that the interlocking members  420  are shaped and sized to conform to one another to facilitate engagement of the first and second support segments  412 ,  414  with one another. In this embodiment, and as illustrated in  FIGS.  29  and  33   , each interlocking member  420  comprises a sidewall  422  and a generally flat top surface  424  respectively configured to engage the corresponding sidewall  422  and top surface  424  of the opposing interlocking member  420 . The sidewalls  422  can be adapted to prevent, or at least reduce, lateral movement and/or rotational movement of the support segments  412 ,  414  relative to one another, while the top surfaces  424  can be adapted to limit vertical movement and/or rotational movement of the support segments  412 ,  414  relative to one another. It is noted that the shape and configuration of the interlocking members do not hinder axial movement of the support segments  412 ,  414  (e.g., along their longitudinal axes) such that the length of the support structure  410  can be adjusted. It is also noted that the offset between the interlocking members  420  (i.e., the distance between the lower and higher interlocking members  420   a,    420   b ) can define a slit  421  extending along the interlocking members  420 . The slit  421  can be adapted to facilitate engagement of the interlocking portions  418  to form the support structure  410 , although it is appreciated that other configurations are possible. 
     Still referring to  FIGS.  28 ,  29  and  33   , in this embodiment, each interlocking member  420  is provided with member apertures  426  adapted to be aligned with the member apertures  426  of the interlocking member  420  positioned above (or below), thereby enabling a fastener (e.g., a nut and screw) to extend through the interlocking members and secure the support segments  412 ,  414  together. In the present embodiment, the stacking assembly  400  includes a support segment latch  430  having a latch body  432  shaped and sized to extend perpendicularly relative to the support segments  412 ,  414 , and engage the higher interlocking members  420   b.  The latch body  432  can be secured to the higher interlocking members  420   b  to secure the support segments  412 ,  414  together. In some embodiments, the latch body  432  includes a pair of latch apertures  433  configured to align with a corresponding pair of member apertures  426 , thereby enabling a fastener (e.g., a nut and screw) to extend through the latch body  432  and the interlocking portions  418  to secure the support segments  412 ,  414  together. It is noted that a plurality of member apertures  426  can be positioned so as to align with one another at any given configuration of the support structure  410 . Therefore, the stacking assembly  400  can include a plurality of support segment latches  430  connectable to the interlocking portions  418  to further secure the support structure  410  in the desired configuration (e.g., at the desired length). 
     In some embodiments, the support segment latch  430  includes a key portion  434  extending from the latch body  432  and configured to engage the support structure  410  in a predetermined configuration to facilitate positioning the latch body  432  perpendicularly across the support segments  412 ,  414 . For example, in the illustrated embodiment of  FIGS.  29  and  33   , the higher interlocking members  420   b  are provided with respective key slots  435 , and the key portion  434  extends downwardly from the latch body  432  and is adapted to engage the key slot  435 . The key portion  434  and the key slot  435  are complementarily shaped so as to enable the key portion  434  to engage the key slot  435  in a predetermined configuration, which positions the latch body  432  perpendicular across the interlocking portions  418 . 
     In some embodiments, the support segment latch  430  can be further adapted to guide the support segments  412 ,  414  during adjustments of the length of the support structure  410 . More particularly, the support segment latch  430  can facilitate axial movement of the support segments  412 ,  414  relative to each other (i.e., facilitate the telescopic movement). In this embodiment, and as seen in  FIG.  29   , the lower interlocking members  420   a  can be provided with a guiding slot  436  extending axially along the length of the corresponding interlocking member. The guiding slot  436  is adapted to align with the key slot  435  of the higher interlocking member  420   b  (i.e., when the first and second support segments are interconnected). Furthermore, the key portion  434  of the support segment latch  430  can be adapted to extend through the key slot  435 , and into the guiding slot  436  of the lower interlocking member  420   a.  It is thus noted that movement of the key potion  434  is restricted to the length of the guiding slot  436 , and that therefore, movement of the support segments  412 ,  414  relative to one another is restricted to the axial direction (i.e., along the longitudinal axis of the support segments). 
     With reference to  FIGS.  34   a  to  34   c   , it is noted that the support segment latch  430  remains perpendicular to the support structure  410  during movement of the support segments  412 ,  414 . Furthermore, positioning the key portion  434  within the key slot  435  position the latch body  432  across the interlocking members  420  (e.g., across the higher interlocking members  420   b ) such that the latch apertures  433  overlay the interlocking members  420 . The support segment latch  430  can thus provide visual indication of the alignment between a given pair of member apertures  426 , where the member apertures  426  will align with the latch apertures  433  and enable fasteners to be introduced through the latch body  432  and interlocking members  420  via the appropriate apertures. As such, the support structure  410  can be operated in various configurations adapted to cooperate with accessories of various sizes. For example, the support structure  410  can be in a central configuration ( FIG.  34   a   ), a lower midsize configuration ( FIG.  34   b   ), a short configuration ( FIG.  34   c   ), and although not illustrated, it is noted that the support structure  410  can be in an upper midsize configuration, a long configuration, and any other suitable configuration adapted for adjusting the length of the support structure. 
     Now referring to  FIGS.  35  to  39   , the support structure  410  is adapted to be connected to at least one of the first accessory  70  (i.e., the accessory positioned below the support structure  410 ), the vehicle surface and a separate component connected to the vehicle surface (e.g., another mounting fixture and/or a rail assembly). In some embodiments, the accessories  70  can be provided with the first and second protruding portions  77 ,  78 , or can be adapted to be mounted on an accessory base  80  comprising the first and second protruding portions  77 ,  78 . As seen in  FIGS.  35  to  39   , the accessory base  80  is illustratively provided below the accessory  70  to facilitate connection of the first and second protruding portions  77 ,  78  with the first and second mounting fixtures. In some embodiments, the support structure  410  is adapted to be connected to the accessory base  80 . For example, and with reference to  FIG.  36   , the stacking assembly  400  can include a support connector  450  coupled between the support structure  410  and the accessory base  80  and configured to maintain the support structure  410  elevated above the accessory base  80 . It is appreciated that maintaining the support structure  410  elevated creates the required space for an accessory  70  to be installed, as seen in  FIGS.  35  and  37   . 
     In this embodiment, the support connector  450  includes a connector plate  452  and one or more connector struts  454  extending downwardly from the connector plate  452  for engaging the accessory base  80 . The connector plate  452  can be connected to the support structure  410  via any suitable means, such as via the fasteners extending through the support segments  412 ,  414  forming the support structure  410 . The one or more connector struts  454  can be connected to the connector plate  452  via similar means, e.g., via fasteners, or can be integrally formed with the connector plate  452 , for example. Furthermore, the connector struts  454  can be secured to the accessory base  80  (or to the vehicle surface) to secure the support structure on the vehicle. It is thus noted that a second accessory  70  can be mounted to the vehicle via the first and second mounting fixtures provided on the support structure  410 . 
     In the illustrated embodiments, the support connector  450  is positioned in the center of the accessory base  80 , and thereby generally in the center of the accessory  70  connected to the accessory base  80 . As such, in some embodiments, the accessories mounted to the vehicle using the mounting system  10  can be provided with a central opening (not shown) to enable the connector struts  454  to extend through the accessory and engage the accessory base  80 . However, in other embodiments, the connector struts  454  can be positioned proximate the ends of the support structure (e.g., proximate the mounting fixtures connected thereto) such that the connector struts  454  can be adapted to extend between the connector plate  452  and accessory base  80  on either side of the accessory (i.e., without going through the accessory). In such embodiments, it is appreciated that the support connector  450  can include a pair of support plates  452  mounted to either ends of the support structure  410 , each provided with one or more connector struts  454 , although other configurations are possible. 
     It is noted that various accessories can be stacked using the mounting system  10  provided with the stacking assembly  400  described herein. For example, gas canisters, storage bins, toolboxes, bags, sporting equipment and any other suitable item can be mounted to the vehicle in a stacked configuration. It is appreciated that the stacking assembly  400  can include a plurality of support structures  410  and support connectors  450  such that two, three, four, or any suitable number of accessories can be stacked on the vehicle. 
     Referring broadly to  FIGS.  28  to  39   , once a first accessory is mounted to the vehicle (e.g., via the mounting fixtures, via the rails or via a combination thereof), a second accessory can be stacked thereon using the stacking assembly  400 . The support structure  410  can first be adjusted based on the size of the second accessory. For example, for large accessories, the support structure  410  can be operated to maximize the distance between the mounting fixtures connected to the support structure. In other words, the length of the support structure  410  is adjusted to the size of the second accessory (or accessory base  80  provided therewith). 
     Once the length of the support structure  410  is determined, the support segments  412 ,  414  can be fastened to one another using the support segment latch  430 , thereby locking the support structure  410  at the desired length. The support structure can then be placed on top of the first accessory, for example, by placing the connector plate  452  on the first accessory  70  and engaging the connector struts  454  with at least one of the accessory base of the first accessory and the vehicle surface. A second accessory, preferably provided with first and second protruding portions, can then be mounted to the vehicle via the mounting fixtures provided on the support structure. It is appreciated that additional accessories can be stacked on the second accessory using another stacking assembly  400  (e.g., another support structure and support connector  450 ). It should also be appreciated that two or more stacks of accessories can be created on the vehicle, either via mounting fixtures connected to different locations on the vehicle surface, or via mounting fixtures connected to different locations along a rail assembly mounted on the vehicle. 
     The present disclosure intends to cover and embrace all suitable changes in technology. The scope of the claims should not be limited by the implementations set forth in the examples but should be given the broadest interpretation consistent with the description as a whole. 
     As used herein, the terms “coupled”, “coupling”, “attached”, “connected” or variants thereof as used herein can have several different meanings depending in the context in which these terms are used. For example, the terms coupled, coupling, connected or attached can have a mechanical connotation.
