     TECHNICAL FIELD 
     Exemplary embodiment(s) of the present disclosure relate to ramp deployment systems and, more particularly, to an automated cargo vehicle ramp deployment system for configured to selectively displace a ramp along a perimeter of a cargo vehicle during loading and unloading operating conditions. 
     BACKGROUND 
     It used to be, if you were moving yourself or needed storage, you had about two options. Option one, rent a vehicle, pick it up, load it up, drive it to the storage unit you rented, unload it, drive back to the vehicle rental place, drive home. And when it was time to pick your stuff up again, well, you know the drill, just in reverse. Option two was, pay through the nose for the luxury of someone to bring a storage unit to you and hope it&#39;s delivered when you need it, have it sit there for a while—good luck with that if you live in an apartment—then hope it&#39;s picked up when you need it gone. 
     Furthermore, different cargo vehicles have loading/unloading doors positioned on different sides of the perimeter of the cargo vehicle. This makes it difficult to use a conventional ramp stored at a rear side of the cargo vehicle. For example, a traditional ramp can weigh between 150-200 lbs. With seven different configurations, the doors can be positioned anywhere on all three sides of the cargo vehicle; on either longitudinal side and the end. Many configurations have multiple doors which will require repositioning the ramp several times. Then depending on the circumstances, the ramp may need to be as short as seven feet and as long as fourteen feet. 
     Accordingly, a need remains for an automated cargo vehicle ramp deployment system in order to overcome at least one of the above-noted shortcomings. The exemplary embodiment(s) satisfy such a need by an automated cargo vehicle ramp deployment system that is convenient and easy to use, durable in design, versatile in its applications, and designed for configured to selectively displace a ramp along a perimeter of a cargo vehicle during loading and unloading operating conditions. 
     SUMMARY 
     In view of the foregoing background, it is therefore an object of the non-limiting exemplary embodiment(s) to provide an automated cargo vehicle ramp deployment system for configured to selectively displace a ramp along a perimeter of a cargo vehicle during loading and unloading operating conditions. These and other objects, features, and advantages of the non-limiting exemplary embodiment(s) are provided by a cargo transport vehicle including at least one cargo transport container, a ramp, a ramp deployment system operably coupled to the ramp and configured to selectively displace the ramp along a perimeter of the at least one cargo transport container, a controller, and a power source in communication with the ramp deployment system. Advantageously, the ramp deployment system is configured to selectively displace the ramp along at least one of a first travel path defined along a perimeter of the at least one cargo transport container, a second travel path defined about a fulcrum pivot axis adjacent to the at least one cargo transport container, and a third travel path defined along a longitudinal length of the ramp and exterior of the at least one cargo transport container. 
     In a non-limiting exemplary embodiment, the ramp deployment system includes a first ramp displacement mechanism configured to selectively displace the ramp from a first position to a second position defined along the first travel path. 
     In a non-limiting exemplary embodiment, the ramp deployment system further includes a second ramp displacement mechanism configured to selectively displace the ramp from one of the first position and the second position to a third position defined along the second travel path. 
     In a non-limiting exemplary embodiment, the ramp deployment system further includes a third ramp displacement mechanism configured to selectively adjust a longitudinal length of the ramp along the third travel path while the ramp is disposed at the third position. Notably, each of the first ramp displacement mechanism, the second ramp displacement mechanism, and the third ramp displacement mechanism is operatively coupled to the controller and the power source, such that a user is able to selectively control the movement of the ramp as desired at the cargo transport container.

Advantageously, the at least one drive motor is configured to displace the trolley in a forward and opposed rearward direction along the guide rail. 
     In a non-limiting exemplary embodiment, the guide rail includes an upper rail and a lower rail each operably coupled to the trolley. 
     In a non-limiting exemplary embodiment, the trolley includes a first roller assembly having a plurality of first bearings and a plurality of first rollers, a second roller assembly having a plurality of second bearings and a plurality of second rollers, and a plurality of motor-mounting plates. Advantageously, the first roller assembly and the second roller assembly are independently pivoted along a first rotation axis and a second rotation axis, respectively, while traveling around a corner of the guide rail along the first travel path. 
     In a non-limiting exemplary embodiment, the trolley includes a center link bracket intermediately disposed between the first roller assembly and the second roller assembly. 
     In a non-limiting exemplary embodiment, the second ramp displacement mechanism includes a ramp pivot shaft pivotally coupled to the trolley, a plurality of ramp pivot blocks engaged with the ramp pivot shaft, a turn buckle operably coupled to the center link bracket, and at least one actuator operably coupled to the turn buckle. Advantageously, the ramp is connected to the turn buckle and the ramp pivot shaft and rotates in clockwise and counterclockwise directions about the fulcrum pivot axis along the second travel path. 
     In a non-limiting exemplary embodiment, the third ramp displacement mechanism includes a plurality of telescopically adjustable support legs attached to the ramp, and a power-drive piston operably coupled to the telescopically adjustable support legs. Advantageously, the telescopically adjustable support legs are configured to selectively extend and retract a longitudinal length of the ramp along the third travel path upon receiving a user input at the controller.

     The non-limiting exemplary embodiment(s) is/are referred to generally in  FIGS. 1-101  and is/are intended to provide a multi-functional cargo transport vehicle  12  including an automated ramp deployment system  10  for facilitating a ramp  11  to traverse at least a portion bed of cargo transport vehicle  12  from a passenger side front, to a rear, to a driver side front and back, to a docking station behind the vehicle  12  on the passenger side. The ramp  11  is preferably electrically operated and rechargeable from a 120v power source. The ramp  11  is preferably telescopic and can extend and retract from 8 ft to 13 ft in length, for example. The ramp  11  may be built from 100% aluminum. 
     In a non-limiting exemplary embodiment, the cargo transport vehicle  12  will not start if the ramp  11  is not secured into the docking station behind the cab of the truck  12 . The ramp  11  will not traverse left/right after being lowered until returned to its upright position. The ramp  11  surface is non-slip for safe loading. The ramp  11  will not extend until it is below parallel to the ground to reduce risk of hitting overhead objects (e.g., trees, power lines etc.). When raising the ramp  11  up, it will also auto retract, again eliminating the risk of hitting objects overhead. Once the ramp  11  touches the ground, safety lights mounted and the top and bottom of the ramp  11  will flash to ensure visibility at night. 
     Non-limiting exemplary embodiments of the present disclosure are referred to generally in  FIGS. 1-101  and is intended to provide an automated cargo vehicle  12  ramp  11  deployment system  10  for configured to selectively displace a ramp  11   11  along a perimeter of a cargo vehicle  12   12  during loading and unloading operating conditions. It should be understood that the exemplary embodiment(s) may be used with a variety of cargo vehicles  12  (trucks, vans, etc.), and should not be limited to any particular cargo vehicle  12  described herein. 
     Referring to  FIGS. 1-101  in general, in a non-limiting exemplary embodiment(s), the automated cargo vehicle  12  may be employed by a self-storage service provider. For example, when a customer is ready to store cargo, simply schedule a time to come pick up a cargo vehicle  12 , with the size storage unit you want, from a closest service provider. Access the self-service lot with a personalized gate code and your vehicle  12  with storage unit will be there waiting for the customer. The cargo vehicles  12  have driver assist safety features, so you&#39;ll feel safe and confident on the road. Simply drive home the cargo vehicle  12 , load it up, lock it up, and bring it back to the service provider lot. A monitoring system notifies the service provider when you&#39;ve returned, and they come right away and take your cargo unit to an indoor climate controlled central storage facility. Customers can visit their stuff whenever they like. Just let the service provider know and they will bring it out to the self-service lot so the customer can spend some quality time. When the customer is finally ready to pick up and unload the cargo unit, just schedule a time and the service provider will have it all ready for the customer at a closest service provider lot. Drive it home, unload and bring it back. 
     Referring to  FIGS. 1-101  in general, the automated cargo vehicle ramp deployment system  10  selectively displaces a ramp  11  along a perimeter of an existing cargo vehicle  12  during loading and unloading operating conditions.

Advantageously, each of the first automated ramp displacement mechanism  21 , the second automated ramp displacement mechanism  22 , and the third automated ramp displacement mechanism  23  is operatively coupled to the controller  13  and the power source  14 .

Advantageously, the controller  13  is configured to enable and disable the user interface upon receiving a corresponding one of the notification signals, respectively, such that each of the first automated ramp displacement mechanism  21 , the second automated ramp displacement mechanism  22 , and the third automated ramp displacement mechanism  23  are enabled and disabled, respectively. 
     In a non-limiting exemplary embodiment, the controller  13  may include programmable software  90  that is launched on a portable electronic device (e.g., mobile phone) for receiving the user input and operating the system  10 . A user interface may be displayed at the controller  13 , such as a graphical user interface. 
     In a non-limiting exemplary embodiment, the power source  14  is operably coupled to an existing power source (e.g., battery, generator, alternator, etc.) of the existing cargo vehicle  12  such that the power source  14  can be recharged as needed. 
     In a non-limiting exemplary embodiment, the first automated ramp displacement mechanism  21  includes a guide rail  35  suitably sized and shaped to extend along a perimeter of the existing cargo vehicle  12 , a trolley (car)  36  operably attached to the ramp  11  and having a plurality of rollers  37  rotatably engaged with the guide rail  35 , and at least one winch  38  having an associated cable  39  operably coupled thereto and positioned along the guide rail  35 . Advantageously, the at least one winch  38  is coupled to the car  36 . In this manner, the at least one winch  38  is configured to wind and unwind the associated cable  39  and thereby displace the car  36  in a corresponding direction along the guide rail  35 , which is extended along the perimeter of the existing cargo vehicle  12 . Advantageously, the trolley  36  and the ramp  11  are simultaneously displaced between the first position  24  and the second position  25 . 
     In a non-limiting exemplary embodiment, a motorized gear and chain mechanism or self-propelled mechanism may be employed to displace the ramp along the perimeter of the cargo vehicle  12 . It is noted that the true spirit and scope of the present disclosure should not be limited by any particular drive mechanism for displacing the ramp  11  along the guide rail  35 . The drive mechanism may be powered or manual, but preferably powered so that safety protocols can be programmed at the controller for limiting unsafe ramp  11  displacement. 
     In a non-limiting exemplary embodiment, the at least one winch  38  includes a first winch  38   a  and a second winch  38   b  in communication therewith. Advantageously, the associated cable  39  includes a first associated cable  39   a  and a second associated cable  39   b  in communication therewith and configured in a substantially figure-eight pattern for pulling the car  36  in opposed directions along the guide rail  35  while prohibiting the first associated cable  39   a  and the second associated cable  39   b  from being undesirably tangled. 
     In a non-limiting exemplary embodiment, the guide rail  35  is extended along at least one side of the cargo vehicle  12 . 
     In a non-limiting exemplary embodiment, the guide rail  35  is extended along at least two sides of the cargo vehicle  12 . 
     In a non-limiting exemplary embodiment, the guide rail  35  is extended along at least three sides of the cargo vehicle  12 . 
     In a non-limiting exemplary embodiment, the second automated ramp displacement mechanism  22  further includes an articulation mechanism (e.g., actuator, hydraulic or pneumatic piston, etc.) operably coupled to the car  36  and the ramp  11  for selectively articulating the ramp  11  between the vertically oriented raised position and the non-vertically oriented position defined below (e.g., declined to the ground surface) a horizontal position relative to the vertically oriented raised position. 
     In a non-limiting exemplary embodiment, the ramp includes a female section  40  and a male section  41  slidably engaged therewith. Advantageously, the third automated ramp displacement mechanism  23  including a ram operably engaged with the female section  40  and the male section  41  and configured to selectively extend and retract the longitudinal length of the ramp  11 . 
     The present disclosure further includes a method of utilizing an automated cargo vehicle ramp deployment system  10  for configured to selectively displace a ramp  11  along a perimeter of an existing cargo vehicle  12  during loading and unloading operating conditions. Such a method includes the steps of: providing a controller  13  and a power source  14  connected thereto; providing and locating a ramp  11  at the existing cargo vehicle  12 ; providing a first automated ramp displacement mechanism  21 ; providing a second automated ramp displacement mechanism  22 ; providing a third automated ramp displacement mechanism  23 ; operatively coupling each of the first automated ramp displacement mechanism  21 , the second automated ramp displacement mechanism  22 , and the third automated ramp displacement mechanism  23  to the controller  13  and the power source  14 ; the first automated ramp displacement mechanism  21  configured to selectively displace the ramp  11  from a first position  24  to a second position  25  defined along a perimeter of the existing cargo vehicle  12  while the ramp is maintained at a vertically oriented position; the second automated ramp  11  displacement mechanism  22  configured to selectively displace the ramp  11  from one of the first position  24  and the second position  25  to a third position  26 , wherein the third position  26  is a non-vertically oriented position; and the third automated ramp displacement mechanism  23  selectively adjusting a longitudinal length of the ramp  11  while the ramp  11  is statically disposed at a third position  26 . 
     During experimentation, many configurations and ramp manufacturers were considered until it was finally decided to design a proprietary ramp  11  and associated displacement mechanisms  21 ,  22 ,  23 . The biggest challenge was making it easy for anyone in any physical condition to both deploy and stow the ramp. In particular, the system  10  stows the ramp  11  in a vertical position behind the cab behind the passenger&#39;s seat but it could also be stored behind the driver&#39;s side of the cab. The operator is presented with a security keypad, primarily intended to make the system  10  child safe. Once the correct code is entered, the operator can transition the ramp  11  in front of a cargo vehicle  12  door of his/her choosing. There are numerous safety features incorporated into the system  10 . For instance, once the ramp  11  is initially moved, the vehicle can no longer be started. Additionally, once the ramp  11  starts to be lowered it can no longer traverse to the next-door position. And of course, there are warning lights and audible signals that activate when appropriate. All of this results in the safe and effortless movement of the ramp  11 . 
     To accomplish displacement of the ramp  11  in a variety of directions, a guide rail  35  and car  36  was developed that could traverse a two-hundred pound plus ramp  11  around a perimeter of the cargo vehicle  12  (vehicle bed) including the corners. The system  10  allows the two-hundred-pound ramp  11  to telescope out to about 14 feet while remaining parallel to the ground, all of which exerts tremendous leverage against the system  10 . To displace, and raise or lower the ramp  11 , hydraulic, pneumatic, gear, and/or ram mechanisms may be employed. It is noted that the specific mechanisms to articulate and extend the ramp  11  is not intended to limit the true scope and spirit of the present disclosure. Of course, a variety of ramp lengths can be employed such as a ramp  11  that can range between twelve and sixteen feet. 
     In a non-limiting exemplary embodiment, the two-hundred-pound telescoping ramp  11  may be extendable from about seven to fourteen feet in longitudinal length. Power-actuated and automated car  36  and rail  35  mechanism  21  displaces the ramp  11  along at least a portion and preferably an entire perimeter of the cargo vehicle  12  is also advantageous. The controller  13  includes a user interface for receiving a plurality of user inputs that instruct various components of the system  10  to operate in a desired mode. For example, the controller  13  deploys the ramp  11  along the perimeter of the vehicle  12  and to a desired position adjacent to the vehicle  12  loading doors, which may be located at one or more sides of the vehicle  12 . Selective powered displacement of the ramp  11  enables loading and unloading of cargo relative to the vehicle  12 . 
     In a non-limiting exemplary embodiment, the ramp  11  is fully automated by a cable-driven car  36  mechanism or other mechanism (first displacement mechanism) along a guide rail  35 , and a telescopically actuated ram mechanism extends and retracts the ramp  11  between minimum and maximum longitudinal lengths, respectively. 
     In a non-limiting exemplary embodiment, winch  38  cables are connected to the other components. For example, the winch cable  39  is positioned along the guide rails  35  and attached to the car  36 , which has rollers  37  wheels that roll along the guide rails  35 . 
     In a non-limiting exemplary embodiment, a ramp  11  ram (third displacement mechanism) is operated by 12-volt linear actuators to extend and retract the longitudinal length of the ramp  11 . Such components simplify the installation and maintenance while also giving a much cleaner presentation to the consumer. Of course, various displacement mechanisms (e.g., hydraulic pistons, pneumatic pistons, worm gears, pulleys, etc.) may be employed without departing from the true spirit and scope of the present disclosure. 
     Advantageously, while ramp  11  is docked, the cargo vehicle  12  will start and the ramp  11  is connected to a proprietary automatic, shock proof, charging system  10  as shown in the figures. Keypad code entry is required to activate the various ramp  11  displacement mechanisms. This provides a child safety feature. The keypad and system  10  deactivate in about 4.5 min+/−. The access code needs to be reentered every time the ramp  11  position is changed. Once activated, the ramp  11  will only move out of the docking station, all other buttons are inactive. When any button is pressed, the lights will flash, and the horn will sound warning bystanders. 
     Once the ramp  11  exits the docking station, all buttons begin to work. The automatic, proprietary, charging system  10  disconnects and deactivates. Now, the cargo vehicle  12  will no longer start. The ramp  11  can be traversed around the entire vehicle bed but will automatically stop prior to reaching the end nearest the driver&#39;s door. The ramp  11  can be lowered at any position along the vehicle bed. Once the ramp  11  begins to lower, it can no longer traverse. It cannot be extended until it is approximately level with the ground. Once the ramp  11  is approximately level with the ground, it may be extended to the desired length. While on the ground, a second set of lights at the tip of the ramp  11  start to flash, warning of a trip hazard. If the customer tries to “ride” the ramp  11  or lift a heavy item, the hydraulic unit will sense it and bypass the system  10 . The deployment process should be reversed to return the ramp  11  to its docking station. However, if the customer attempts to raise the ramp  11  prior to retracting it, the ramp  11  will automatically retract. Once the ramp  11  is fully raised it can be traversed back to is docking station. The ramp  11  will automatically stop when docked and reconnect itself to the charging station. The vehicle will now start. 
     In a non-limiting exemplary embodiment, the controller  13  may be programmed to automatically dock the ramp  11  via a single user input (e.g., single button). 
     Referring to  FIGS. 1-101  in general, a cargo transport vehicle  12  is disclosed, which includes at least one cargo transport container  55 , a ramp  11 , a ramp deployment system  10  operably coupled to the ramp  11  and configured to selectively displace the ramp  11  along a perimeter  56  of the at least one cargo transport container  55 , a controller  13 , and a power source  14  in communication with the ramp deployment system  10 . Advantageously, the ramp deployment system  10  is configured to selectively displace the ramp  11  along at least one of a first travel path  31  defined along a perimeter  56  of the at least one cargo transport container  55 , a second travel path  32  defined about a fulcrum pivot axis  45  adjacent to the at least one cargo transport container  55 , and a third travel path  33  defined along a longitudinal length of the ramp  11  and exterior of the at least one cargo transport container  55 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof, as well as lower the ramp  11  and extend/retract the ramp  11 , as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the ramp deployment system  10  includes a first ramp displacement mechanism  21  configured to selectively displace the ramp  11  from a first position  24  to a second position  25  defined along the first travel path  31 . For example, the ramp  11  may be displaced from an initial resting position to a final position in front of an access door  98 . As another non-limiting example, ramp  11  may be displaced from around a corner segment of the guide rail  35  to a linear segment of the guide rail  35 . The ramp  11  is preferably in a vertical orientation during displacement between positions  24  and  25 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof while the ramp is in a vertical position (e.g., from a left side to a rear of the cargo transport container). 
     In a non-limiting exemplary embodiment, the ramp deployment system  10  further includes a second ramp displacement mechanism  22  configured to selectively displace the ramp  11  from one of the first position  24  and the second position  25  to a third position  26  (e.g., non-vertical position such as horizontal and declined positions) defined along the second travel path  32 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof, (e.g., lower the ramp  11  from a vertical position to a lowered position for loading/unloading cargo), as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the ramp deployment system  10  further includes a third ramp displacement mechanism  23  configured to selectively adjust a longitudinal length of the ramp  11  along the third travel path  33  while the ramp  11  is disposed at the third position  26  (e.g., lengthen/shorten the ramp  11  for uneven ground surfaces such as when the ramp  11  is rested on a stairway, street curb, unloading dock, etc.). Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly extend/retract the ramp  11 , as needed, and without exerting undue energy. 
     Notably, each of the first ramp displacement mechanism  21 , the second ramp displacement mechanism  22 , and the third ramp displacement mechanism  23  is operatively coupled to the controller  13  and the power source  14 , such that a user is able to selectively control the movement of the ramp  11  as desired at the cargo transport container  55 . The controller  13  preferably includes a processor and memory containing software instructions executable by the processor in response to a user input. The guide rail  35  may have a support frame  85  that sits on the vehicle  12  chassis or bed for receiving and supporting at least one cargo transport container  55  thereon via a fastening mechanism  86  (e.g., ratchets, anchor bars, straps, etc.). Of course, a variety of suitable fastening mechanism may be employed to anchor the cargo transport container  55  to the support frame  85 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and remotely control ramp  11  movement, as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the first ramp displacement mechanism  21  includes a guide rail  35  attached to at least a portion of a perimeter  56  of the existing cargo transport vehicle  12  (via support frame  85 ), a trolley  36  operably attached to the ramp  11  and having a plurality of rollers  37  rotatably engaged with the guide rail  35 , and at least one drive motor  58  operably coupled to the trolley  36  and positioned along the guide rail  35 . Advantageously, the at least one drive motor  58  is configured to displace the trolley  36  in a forward and opposed rearward direction along the guide rail  35 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof, (e.g., displace the ramp around a corner of the guide rail), as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the guide rail  35  includes an upper rail  35   a  and a lower rail  35   b  each operably coupled to the trolley  36 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to maintain the trolley  36  securely engaged with the ramp  11 . 
     In a non-limiting exemplary embodiment, the trolley  36  includes a first roller assembly  60  having a plurality of first bearings  61  and a plurality of first rollers  62 , a second roller assembly  65  having a plurality of second bearings  66  and a plurality of second rollers  67 , and a plurality of motor-mounting plates  68 . Advantageously, the first roller assembly  60  and the second roller assembly  65  are independently pivoted along a first rotation axis  70  and a second rotation axis  71 , respectively, while traveling around a corner of the guide rail  35  along the first travel path  31  (see  FIGS. 31, 97-98 ). Notably, the first roller assembly  60  and second roller assembly  65  are registered orthogonal  99  relative to the fulcrum pivot axis  45  when the trolley  36  travels along a linear portion of the guide rail  35 . Alternately, the first roller assembly  60  and second roller assembly  65  are registered at oblique angles  99   a  relative to the fulcrum pivot axis  45  when the trolley  36  travels along a curvilinear portion (corner) of the guide rail  35 . Such a morphed shaped of trolley  36  allows the ramp  11  to travel along curvilinear and space-limited travel paths (e.g., the corner of the guide rail  35 ). Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof, (e.g., displace the ramp around a corner of the guide rail), as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the trolley  36  includes a center link bracket  75  intermediately disposed between the first roller assembly  60  and the second roller assembly  65 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof, (e.g., displace the ramp around a corner of the guide rail), as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the second ramp displacement mechanism  22  includes a ramp pivot shaft  76  pivotally coupled to the trolley  36 , a plurality of ramp pivot blocks  77  engaged with the ramp pivot shaft  76 , a turn buckle  78  operably coupled to the center link bracket  75 , and at least one actuator  79  (motor) operably coupled to the turn buckle  78 . Advantageously, the ramp  11  is connected to the turn buckle  78  and the ramp pivot shaft  76  and rotates in clockwise and counterclockwise directions  83  about the fulcrum pivot axis  45  along the second travel path  32  for raising and lowering the ramp  11  between vertical and declined positions, respectively. Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly displace the ramp  11  to a desired position along a perimeter of the cargo transport container  55  proximate to an access door  98  thereof, (e.g., lower the ramp  11  from a vertical position to a lowered position for loading/unloading cargo), as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the third ramp displacement mechanism  23  includes a plurality of telescopically adjustable support legs  80  attached to the ramp  11 , and a power-drive piston (motor)  82  operably coupled to the telescopically adjustable support legs  80 . Advantageously, the telescopically adjustable support legs  80  are configured to selectively extend and retract a longitudinal length of the ramp  11  along the third travel path  33  upon receiving a user input at the controller  13 . Such a structural configuration provides the new, useful, and unexpected result of enabling a user to safely and succinctly extend/retract the ramp  11  when the vehicle  12  is position on a non-horizontal surface, as needed, and without exerting undue energy. 
     In a non-limiting exemplary embodiment, the controller  13  contains suitably circuitry, (e.g.,  94  at  FIG. 42 ), in communication with electronic equipment such motors, actuators, power sources, user interfaces, lights, alarms, cameras, transceivers, transducers, etc. thereby enabling a user to safely and succinctly operate the system  10 . A housing  92  is provided with apertures  93  to pass through electrical wiring as needed. Transceiver  95  communicates operating parameters data to and from the controller  13 . 
     In a non-limiting exemplary embodiment, ramp  11  may have a pivotal flap, bridge, or extension  81  for covering a gap (threshold) transition between the ramp  11  and cargo transport container  55 . 
     Referring to  FIGS. 99-101 , in a non-limiting exemplary embodiment, an optional vertical ramp lifting mechanism  110  is illustrated, which can be attached to the guide rail  35  and/or linked to the trolley  36 . Alternately, the vertical ramp lifting mechanism  110  may be independently operated, from the trolley  36 , along guide rail  35 . The vertical ramp lifting mechanism  110  may include an anchor plate  112  securely affixed to the vehicle  13  (via guide rail  35  and/or trolley  36 ) and preferably spaced from the cargo transport container  55 . A rectilinear crossbar  113  is statically mated to the anchor plate  112  and has axially opposed ends positioned anterior of the anchor plate  12 . The crossbar  113  has a longitudinal length at least as wide as the ramp  11 . A pair of lift assemblies  114 ,  115  are operably connected to the axially opposed ends of the crossbar  113 . Each of the lift assemblies  114 ,  115  may include an actuator  116  suitably sized and shaped to vertically lift a combined weight of the ramp  11  and cargo supported thereon. Suitable actuators  116  may include drive motors, worm gears, hydraulic pistons, pneumatic pistons, pulleys, beveled gears, and chains, for example. The specific configuration of the suitable actuators  116  is not intended to limit the true spirit and scope of the lift assemblies  114 ,  115 . Notably, as the ramp  11  is vertically lifted, the bridge  81  automatically falls into place and covers the threshold transition between the ramp  11  and the cargo transport container  55 . 
     The vertical ramp lifting mechanism  110  may be power operated via the same power source as the ramp deployment system  10  or may operate under a separate dedicated power source. Of course, the vertical ramp lifting mechanism  110  may be manually operated without the need to drive it via a power source. 
     In a non-limiting exemplary embodiment, the ramp  11  may be retrofitted with a conveyor belt mechanism  117  for easily and succinctly transporting cargo along a longitudinal length of the ramp  11 . Such a conveyor belt mechanism  117  may operate by using two motorized pulleys that loop over a long stretch of thick, durable material. When motors in the pulleys operate at the same speed and spin in the same direction, the belt moves between the two. The conveyor belt mechanism  117  may be power operated via the same power source as the ramp deployment system  10  or may operate under a separate dedicated power source 
     In a non-limiting exemplary embodiment, each of the vertical ramp lifting mechanism  110  and conveyor belt mechanism  117  may be operated via the controller  13  (e.g., software app) upon receiving a user input. 
     While non-limiting exemplary embodiment(s) has/have been described with respect to certain specific embodiment(s), it will be appreciated that many modifications and changes may be made by those of ordinary skill in the relevant art(s) without departing from the true spirit and scope of the present disclosure. It is intended, therefore, by the appended claims to cover all such modifications and changes that fall within the true spirit and scope of the present disclosure. In particular, with respect to the above description, it is to be realized that the optimum dimensional relationships for the parts of the non-limiting exemplary embodiment(s) may include variations in size, materials, shape, form, function and manner of operation. 
     The Abstract of the Disclosure is provided to comply with 37 CFR § 1.72(b) and is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims. In addition, in the above Detailed Description, various features may have been grouped together or described in a single embodiment for the purpose of streamlining the disclosure. This disclosure is not to be interpreted as reflecting an intention that the claimed embodiment(s) require more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive subject matter may be directed to less than all of the features of any of the disclosed non-limiting exemplary embodiment(s). Thus, the following claims are incorporated into the Detailed Description, with each claim standing on its own as defining separately claimed subject matter. 
     The above disclosed subject matter is to be considered illustrative, and not restrictive, and the appended claims are intended to cover all such modifications, enhancements, and other embodiment(s) which fall within the true spirit and scope of the present disclosure. Thus, to the maximum extent allowed by law, the scope of the present disclosure is to be determined by the broadest permissible interpretation of the following claims and their equivalents, and shall not be restricted or limited by the above detailed description.
