Title: Adaptable hitch system

Description:
TECHNICAL FIELD 
     The present application relates to a hitch system for a vehicle, and more particularly to a hitch system for attaching an implement or accessory to a vehicle. 
     BACKGROUND 
     There are a variety of conventional hitch constructions for vehicles. Two of these conventional hitch types have reached a near ubiquitous level of recognition: (1) a trailer hitch having a receiver for receiving a shank and (2) a fifth wheel hitch. A third, less recognized conventional hitch is a custom hitch assembly designed to accommodate a particular vehicle and implement or accessory configuration. Each of these conventional hitches is often times used for one or more particular fields. For example, the conventional trailer hitch in many instances receives a shank attached to an accessory, such as a drawbar with a ball mount located proximate to an end of the shank. Accessory configurations can vary from application to application. To provide some additional examples, the drawbar can be used to tow a boat trailer, or the accessory can be a bike rack or cargo carrier. The conventional trailer hitch provides a single point connection to the vehicle—via the receiver—and therefore the type of accessories used in connection with this conventional trailer hitch are often times limited to accessories that do not require significant lateral stability or significant lateral loads. For example, a conventional trailer hitch is considered effective in towing applications, but less effective in the realm of a plow implement that exerts downward force or is subjected to lateral forces or loads. 
     The conventional trailer hitch, itself, may be mounted to the rear frame of the vehicle. There are several classes or variations of the trailer hitch, but a 2 in. by 2 in. receiver or a Class III or IV trailer hitch is one of the more common constructions. Many trucks and sport utility vehicles are fitted with such a Class III or IV trailer hitch. The Class of this type of conventional trailer hitch is generally indicative of the weight capacity of the hitch and the receiver size. There are several additional classes, such as Class I or Class V, trailer hitches available, depending on the application and desired weight carrying capacity. 
     The fifth wheel hitch, another conventional hitch, can be used in various towing applications, such as to tow a semi-trailer or recreational vehicle. The fifth wheel hitch utilizes a single point connection like the conventional trailer hitch, but, in some cases, provides greater towing stability over the conventional trailer hitch. Rather than the receiver and shaft construction of the trailer hitch, the conventional fifth wheel hitch utilizes a horseshoe shaped coupler that rotates to capture a kingpin mounted to the accessory being linked to the fifth wheel hitch. The conventional fifth wheel hitch construction is used in nearly all semi-trailer trucks or tractors on the road today in the U.S. The conventional fifth wheel hitch construction has also been used in the realm of pickup trucks or a truck having an open bed. The fifth wheel hitch can be mounted on two rails located on the truck bed and coupled to the frame of the truck through the truck bed. Because trucks of different makes can have different dimensions, the position of the rails, and therefore the fifth wheel hitch, within the truck bed often times varies between truck makes. Although the conventional fifth wheel hitch may offer additional stability over the conventional vehicle trailer hitch, conventional fifth wheel hitches, like the conventional vehicle trailer hitch, are used primarily for towing, and therefore tend to be less stabile when subjected to lateral loads. Further, the kingpin is allowed to rotate within the fifth wheel to facilitate traversing turns while towing an accessory, such as a trailer. In this way, the accessory is capable of rotating or pivoting about the fifth wheel. 
     In circumstances in which a hitch accessory or implement is not configured to interface with a conventional trailer hitch or fifth wheel hitch, a custom hitch can be constructed according to the specific dimensions of the hitch accessory and the vehicle to which the hitch accessory or implement is being attached. For example, custom hitches are often times used in conjunction with rear mounted snowplow accessories. As mentioned herein, trucks of different makes can have different dimensions, such as different frame locations and truck bed configurations. Because rear mounted snowplow accessories can be subjected to lateral loads or configured to exert downward forces, the single point connection offered by the conventional trailer hitch or fifth wheel hitch can be insufficient to provide an effective connection. The custom hitch may include more than one connection point, and therefore is considered to offer stability over these conventional standard hitches. However, construction of a custom hitch in many cases is laborious and involves custom fabrication of a construction specific to both the make of vehicle and the snowplow dimensions. Further, reuse of the custom hitch in connection with a different vehicle make or a different snowplow can be encumbered or impossible without significant effort or rework of the custom hitch. As a result, upgrades to vehicles or snowplows within a fleet of snowplow vehicles can be costly in terms of additional labor to construct new custom hitches. 
     SUMMARY OF THE DESCRIPTION 
     The present disclosure is directed toward a vehicle accessory hitch assembly for attaching an accessory to a vehicle. The vehicle may include a frame and a bed mounted to the frame. First and second base rails may be disposed on the bed and coupled to the frame of the vehicle, and the vehicle may include a vehicle trailer hitch with a receiver for accepting a shank. In one embodiment, the vehicle accessory hitch assembly may be mechanically connected to each of the first and second base rails and the vehicle trailer hitch such that the vehicle accessory hitch assembly is immovable or stationary relative to the first and second base rails and the vehicle trailer hitch. In another embodiment, the vehicle accessory hitch assembly may be adaptable to connect to differently-configured base rails and vehicle trailer hitch constructions, including different horizontal and vertical spacing between the base rails and the vehicle trailer hitch. 
     In one aspect, the vehicle accessory hitch assembly may include a first member opposing a second member, where each of the first and second members includes a bed section and a rear section. The bed section may be configured to extend along the bed of the vehicle, and the rear section may be configured to be in proximity to the rear of the vehicle. Each bed section of the first and second members may fixedly couple to the first and second base rails of the vehicle. The vehicle accessory hitch assembly may further include a hitch support fixedly coupled to the rear section of the first member and the rear section of the second member. The hitch support may include a shank member configured to interface with the receiver of the vehicle trailer hitch. With this configuration, the vehicle accessory hitch assembly may be configured to fixedly couple to the first base rail of the vehicle and the second base rail of the vehicle. In one embodiment, the vehicle trailer hitch assembly may be fixedly coupled to these components of the vehicle such that the vehicle accessory hitch assembly is immovable or stationary relative to the first base rail, the second base rail, and the vehicle trailer hitch. 
     In one embodiment, the vehicle accessory hitch assembly may include an accessory support fixedly coupled to the first member, the second member and the hitch support, where the accessory support may be configured to connect to and support a vehicle accessory near the rear of the vehicle. 
     The vehicle accessory hitch assembly in one embodiment may be adaptable such that different horizontal and vertical spacing between the base rails and the vehicle trailer hitch may be accommodated. The bed sections of the first and second members may be adjustable in length enabling use of the vehicle accessory hitch assembly with different horizontal spacing between the base rails and the vehicle trailer hitch (or the rearmost part of the vehicle). For example, the spacing between the base rails and the vehicle trailer hitch may be longer for one vehicle than another vehicle. Because the bed sections may be adjustable in length, several different types of vehicle configurations may be used in conjunction with the vehicle accessory hitch assembly. The hitch support of the vehicle accessory hitch assembly may be constructed to allow vertical adjustment of the shank relative to the bed sections of the first and second members. Similar to the distance or spacing between the base rails and the vehicle trailer hitch, the position of the vehicle trailer hitch relative to the bed of the vehicle may be different for one vehicle than another vehicle. In being configured to allow vertical adjustment of the shank, the vehicle accessory hitch assembly may be fitted to both vehicles. 
     In one aspect, a method of attaching a vehicle accessory hitch to the vehicle includes fixedly coupling a first hitch member to each of the first and second base rails such that the first hitch member is stationary relative to the first and second base rails, where the first hitch member includes a first bed section extending along the bed of the vehicle and includes a first rear section disposed in proximity to a rear of the vehicle. 
     The method further includes fixedly coupling a second hitch member to each of the first and second base rails such that the first hitch member is stationary relative to the first and second base rails, the second hitch member being in an opposing position relative to the first hitch member, and where the first hitch member includes a second bed section extending along the bed of the vehicle and includes a second rear section disposed in proximity to a rear of the vehicle. The method may also include attaching an accessory support to the first and second hitch members, the accessory support being configured to enable mounting of a vehicle accessory to the vehicle accessory hitch, and inserting a shank member into the receiver of the vehicle trailer hitch to aid in mechanically stabilizing the first and second hitch members relative to the vehicle trailer hitch. The shank member may be stationary relative to the accessory support. 
     In one aspect, a vehicle accessory hitch assembly may be fitted to several different make and model vehicles, each with potentially different constructions. The vehicle accessory hitch assembly may be adaptable to the different make and model vehicles thereby potentially avoiding fabrication of a custom hitch for each vehicle. Reuse of the vehicle accessory hitch assembly with different vehicles may be possible because the vehicle hitch is adaptable. Further, vehicle accessory hitch assembly may be mechanically connected to several parts of the vehicle in a manner that withstands substantial transverse loading or in an immovable, stationary manner. 
     These and other advantages and features of the invention will be more fully understood and appreciated by reference to the description of the current embodiment and the drawings. 
     Before the embodiments of the invention are explained in detail, it is to be understood that the invention is not limited to the details of operation or to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings.

     DESCRIPTION 
     An accessory hitch system for attaching an accessory to a vehicle is shown in  FIG. 1 , and is generally designated  100 . The accessory hitch system  100  includes a vehicle accessory hitch assembly  110 , a vehicle  10  and an accessory  30 . The vehicle accessory hitch assembly  110  may be connected to the vehicle  10  in a variety of ways, as discussed herein, and may facilitate attachment of the accessory  30  to the vehicle  10 . In one aspect, the vehicle accessory hitch assembly  110  may be coupled to the vehicle frame and a vehicle trailer hitch  18  in a fixed manner such that the vehicle accessory hitch assembly  110  is substantially immovable relative to the vehicle frame and the vehicle trailer hitch  18 . In another aspect, the vehicle accessory hitch assembly  110  may be adjustable to accommodate different spacing between the frame mounting points and the vehicle trailer hitch. Different vehicle heights may also be accommodated by adjustment. 
     In the illustrated embodiment, the accessory hitch system  100  may include a control system  12  configured to allow an accessory operator to control operation of the accessory  30 , including, for example, enabling control over one or more actuators coupled between the vehicle accessory hitch assembly  110  and the accessory  30 . The control system  12  may operate in conjunction with an accessory actuator system  112  to control operation of the accessory  30 . The accessory actuator system  112  may be operably connected to the accessory  30  to receive and carry out instructions from the control system  12 . The accessory actuator system  112 , in one embodiment, may transmit information (e.g., diagnostic information or status information, or both) to the control system  12 . 
     For purposes of disclosure, the accessory  30  is shown as a rear mounted snowplow, but it should be understood that the accessory  30  may be any type of accessory or implement. Some example accessories or implements include cargo carriers, storage boxes, trailers and agricultural implements. 
     In the illustrated embodiment of  FIG. 1 , and as shown in further detail in  FIG. 3 , the accessory hitch system  100  may include a first base rail  14  and a second base rail  16  disposed on a bed  20  of the vehicle  10 , and coupled to the frame (not shown) of the vehicle. The first and second base rails  14 ,  16  may include several aperture and hitch pin hole configurations enabling various connection configurations between the first and second base rails  14 ,  16  and a vehicle accessory hitch assembly  110 . Apertures  17  of the first and second base rails  14 ,  16  may be spaced along the length of the first and second base rails  14 ,  16 , and hitch pin holes  15  may be transversely aligned with the apertures  17  to facilitate a mechanical connection between the first and second base rails  14 ,  16  and a coupler  150  of the vehicle accessory hitch assembly  110 . By having a plurality of apertures  17  and associated hitch pin holes  15 , the first and second base rails  14 ,  16  may accommodate different connection configurations. It should be understood that the first and second base rails  14 ,  16  may be configured differently to include more or fewer apertures  17  and associated hitch pin holes  15 . 
     In the illustrated embodiment, the apertures  17  of the first and second base rails  14 ,  16  are configured to receive an end of the coupler  150 , which may include a coupler hole  154 ,  158  that, after being inserted into one of the apertures  17 , aligns with the hitch pin holes  15 . A hitch pin  152  can be inserted through the hitch pin holes  15  and the coupler hole  154 ,  158  to form a mechanical connection between the first and second base rails  14 ,  16  in the vehicle accessory hitch assembly  110 . 
     The first and second base rails  14 ,  16  may be mechanically coupled to a frame (not shown) of the vehicle  10  using one or more fasteners. In many cases, vehicle manufacturers provide mounting locations for rails, such as the first and second base rails  14 ,  16 , to the vehicle frame. This practice is often implemented in connection with pickup trucks, similar to the pickup truck shown in  FIG. 1 . The first and second base rails  14 ,  16  can be fastened to the mounting locations through the bed of the vehicle. In this way, a rigid mechanical connection can be formed between the first and second base rails  14 ,  16  and the frame of the vehicle  10 . Vehicle constructions often differ between makes and models, and so the mounting locations for the first and second base rails  14 ,  16  for one model vehicle may be different from that of another model vehicle. As a result, the distance between the rear of the vehicle and the mounted position of the first and second base rails  14 ,  16  may vary among vehicle makes and models. Likewise, the distance between the mounted position of the first and second base rails  14 ,  16  and the vehicle trailer hitch  18  may vary among vehicle makes and models. As discussed herein, the vehicle accessory hitch  110  may be adjustable to accommodate such variations among vehicle makes and models. 
     In one embodiment, the first and second base rails  14 ,  16  may be conventional rails configured to connect with a fifth wheel hitch, such as the conventional fifth wheel rails sold by Reese®, and conventionally known as Reese® fifth wheel rails. In this embodiment, the distance between the first and second base rails  14 ,  16  may be a standard distance sized to accommodate the conventional mounting spacing for the conventional fifth wheel hitch, which, as discussed above, provides a single point about which an accessory can rotate. Although the spacing between the first base rail  14  and the second base rail  16  may be standard in this embodiment, the distance between (a) the first and second base rails  14 ,  16  and (b) the rear of the vehicle may vary among vehicle makes and models, as discussed above. 
     The vehicle accessory hitch assembly  110  is shown in further detail in the illustrated embodiments of  FIGS. 2 and 3 . In the illustrated embodiments, the vehicle accessory hitch assembly  110  may include a first beam  130 , a second beam  140 , a first elongate member  132 , a second elongate member  142 , a brace  120 , an accessory support  170  and a hitch support  180 . A vehicle accessory hitch assembly  110  according to one embodiment may enable a rigid, immovable connection between (a) the vehicle accessory hitch assembly  110  and (b) the first base rail  14 , the second base rail  16 , and the vehicle trailer hitch  18 . 
     The vehicle accessory hitch assembly  110  may be adjustable or adaptable to accommodate different spacing or distances among one or more of the first base rail  14 , the second base rail  16 , and the vehicle trailer hitch  18 . For example, the first beam  130  and the first elongate member  132  may be fastened to each other to form a first hitch member having a bed section disposed in proximity to and extending substantially along the bed  20  of the vehicle  10 , and having a rear section in proximity to the rear of the vehicle  10 . The rear section of the first hitch member may overhang at least a portion of the rear of the vehicle  10 . To accommodate different distances between the first and second base rails  14 ,  16  and the rear of the vehicle, the bed section of the first elongate member may be variable in length. In particular, the first beam  130  and the first elongate member  132  may be configured to connect to each in a plurality of positions such that the overall length of the bed section, formed in connecting the first beam  130  in the first elongate member  132 , may vary. The second beam  140  and the second elongate member  142  may be constructed in a manner similar to the first beam  130  and the first elongate member  132 , and may be fastened to each other to form a second hitch member having a bed section disposed in proximity to and extending along the bed  20  of the vehicle  10 , and having a rear section in proximity to the rear of the vehicle  10 . The bed sections and the rear sections, or a subset thereof, of the first and second hitch members may be immovably attached to the vehicle  10 . Because the first and second hitch members are spaced apart from each other, and/or because each of the first and second members is coupled to the first base rail  14 , the second base rail  16 , and the vehicle trailer hitch  18 , the vehicle accessory hitch assembly  110  may be capable of withstanding transverse loading on the accessory  30 , or loading generally parallel to a side of the vehicle  10 . 
     The first elongate member  132  according to one embodiment is shown in  FIGS. 11, 12 and 17 . The first elongate member  132  may include a first connection member  134  and a second connection member  136  disposed transverse to a longitudinal axis of the first elongate member  132 . In the illustrated embodiment, in manufacturing the first elongate member  132 , the first and second connection members  134 ,  136  may be inserted within respective slots, and then welded in place. The first and second connection members  134 ,  136  may provide attachment points for connecting the first elongate member  132  to the first and second base rails  14 ,  16 . For example, the first connection member  134  may be fastened to a coupler  150  configured to attach to the first base rail  14  using a hitch pin  152 , as discussed herein. And, the second connection member  136  may be fastened to another coupler  150  configured to attach to the second base rail  16  using a hitch pin  152 , as discussed herein. It should be understood that the present disclosure is not limited to a particular type of coupling or connection between the first elongate member  132  and the first and second base rails  14 ,  16 , and that any type of coupling or connection may be used. 
     In the illustrated embodiment of  FIGS. 11 and 18 , the first elongate member  132  may include a plurality of slots  131 . The plurality of slots  131  may be spaced from one another along the longitudinal axis of the first elongate member  132 . In this way, the plurality of slots  131  may provide a plurality of locations along the longitudinal axis at which the first elongate member  132  can be connected to the first beam  130 . In the illustrated embodiment, the plurality of slots  131  are each approximately 2 inches in length, and spaced approximately 1 inch from each other along the longitudinal axis of the first elongate member  132 . The length of the slots  131  and the spacing therebetween may vary depending on the configuration. 
     A second elongate member  142 , in one embodiment, may be substantially identical to the first elongate member  132 , and is shown connected to a second beam  140  in the illustrated embodiments of  FIGS. 5 and 6  in a manner similar to the connection between the first elongate member  132  and the first beam  130 . The first elongate member  132  may be symmetrical about the longitudinal axis such that, by flipping the first elongate member  132 , the first elongate member  132  may be used as the second elongate member  142 , and may be mounted to the first and second base rails  14 ,  16  in proximity to the bed  20  in a manner that opposes the first elongate member  132 . As a result, the first and second elongate members  132 ,  142  can be respectively manufactured as one component. 
     The first beam  130  according to one embodiment is shown in  FIGS. 17 and 18 . In the illustrated embodiment, the first beam  130  may comprise a bed member  192  and a support member  190 . The bed member  192  may be constructed to be fastened to the first elongate member  132  such that the bed member  192  is substantially aligned with the longitudinal axis of the first elongate member  132 . The support member  190  and the bed member  192  may form a right angle such that, when installed on the vehicle  10 , the bed member  192  is in proximity to the rear of the vehicle and substantially perpendicular to a plane defined by the bed  20  or the ground over which the vehicle  10  is disposed. It should be understood that the present disclosure is not limited to a right angle or perpendicular configuration, and that the angle between the bed member  192  and the support member  190  may vary from configuration to configuration. For example, among different constructions, the angle may vary from 0° to 100° relative to the longitudinal axis of the bed member  192 . In practical terms, the support member  190  may be configured in any manner that enables the vehicle accessory hitch assembly  110  to be attached to the first and second base rails  14 ,  16  and the vehicle trailer hitch  18 . 
     The first beam  130  may include a plurality of mounting holes  196 A-G spaced apart from one another, and capable of interfacing with a fastener, such as a bolt and nut, to fasten the first beam  130  the first elongate member  132 . The plurality of mounting holes  196  A-G may be spaced in a manner to correspond with the plurality of slots  131  so that at least two of the mounting holes  196  A-G may be aligned with corresponding slots  131  irrespective of the relative position between the first beam  130  and the first elongate member  132 . In other words, in one embodiment, over a range extending from the longest to shortest configuration of the bed section formed by the first beam  130  and the first elongate member  132 , the positions of the plurality of slots  131  and the mounting holes  196 A-G may enable substantially unlimited adjustability while enabling a substantially firm mechanical connection therebetween. In the illustrated embodiment, the mount holes  196 A-B are 2 inches apart, center to center. Likewise, the mounting holes  196 D-E and the mounting holes  196 F-G are respectively 2 inches apart, center to center. The mounting holes  196 B-C, the mounting holes  196 C-D are the mounting holes  196 E-F are respectively 8 inches apart, center to center. It should be understood that the spacing among the mounting holes  196 A-F may vary from application to application. 
     The support member  190  of the first beam  130  may include a plurality of slots  198  configured to align with mounting holes of the accessory support  170  so that the accessory support  170  can be fastened to the first beam  130 . The plurality of slots  198  may be generally spaced and configured in a manner similar to the slots  131 . However, at least two of the plurality of slots  198  may have a different spacing from the other plurality of slots  198  to facilitate adjustability in mounting the accessory support  170  relative to the first beam  130 . 
     The first beam  130  may also include a brace mounting hole  194  that aligns with a corresponding mounting hole in the brace  120  so that the brace  120  can be affixed to the first beam  130  using a fastener, such as a bolt and nut  147 . 
     In the illustrated embodiment, the transition between the bed member  192  and the support member  190  is continuous or formed without the use of a mechanical joint between the bed member  192  in the support member  190 . The inside and outside radiuses of the transition, in the illustrated embodiment of  FIG. 16 , may be different so that additional material may be incorporated into the transition, thereby strengthening the transition between the bed member  192  and the support member  190 . In this way, a mechanical joint between the bed member  190  and the support member  192  may be avoided, and the first beam  130  can be manufactured with the bed member  192  and the support member  190  as a single component. 
     Similar to the first and second elongate members  132 ,  142 , the first beam  130  may be substantially identical to the second beam  140 . As a result, the first beam  130  and the second beam  140  may be interchangeable. It should be understood, however, that, like the first and second elongate members  132 ,  142 , the first and second beams  130 ,  140  may be configured differently from each other. 
     In the illustrated embodiment of  FIGS. 3 and 9-10 , the vehicle accessory hitch assembly  110  includes a brace  120  disposed between (a) the first beam  130  and the first elongate member  132  and (b) the second beam  140  and the second elongate member  142 . The brace  120  may be sized to couple to inside, opposing faces of the first elongate member  132  and the second elongate member  142 , and to couple to inside opposing faces of the first beam  130  and the second beam  140 . The brace  120  may be formed by overlapping and welding two members  121 ,  123  in a cross-halved joint configuration. Each end of the members  121 ,  123  may be connected to a mounting plate  122 ,  124 ,  126 ,  128 . In the illustrated embodiment, the mounting plates  126 ,  128  are configured to be mechanically fastened to the first and second elongate members  132 ,  142 , respectively. And, the mounting plates  122 ,  124  are configured to be mechanically fastened to the first and second beams  130 ,  140 , respectively. As discussed herein, the vehicle accessory hitch assembly  110  may be configured to resist transverse loading, or loads applied in a direction perpendicular to a side of the vehicle  10 . Incorporation of the brace  120 , and its attachment to the first and second elongate members  132 ,  142  and the first and second beams  130 ,  140  may further strengthen the vehicle accessory hitch assembly  110  against such transverse loading. The mounting plates  122 ,  124 ,  126 ,  128  may include mounting holes configured and spaced in a manner similar to the mounting holes described herein in connection with the first and second elongate members  132 ,  142  and the first and second beams  130 ,  140 . 
     In the illustrated embodiments of  FIGS. 2, 8 and 13-15 , the accessory support  170  of the vehicle accessory hitch assembly  110  is shown in further detail. The accessory support  170  may include a first end plate  172 , a second end plate  174  and a shank mount  176  disposed between the first end plate  172  and the second end plate  174 . The first end plate  172  may be affixed to the support member  190  of the first beam  130 , and the second end plate  174  may be affixed to the support member  190  of the second beam  140 . It should be understood that these components can be affixed together in a variety of ways; in the illustrated embodiment, a bolt and nut fastener in conjunction with slots and mounting holes are used. However, the present disclosure is not so limited. With the accessory support  170  being mounted to the support members  190  of the first and second beams  130 ,  140 , the accessory support  170  may be positioned near the rear of the vehicle  10 . In particular, in one embodiment of this configuration, the accessory support  170  may be positioned and held at the rear of the vehicle  10 . 
     To further support the vehicle accessory hitch assembly  110 , including the accessory support  170 , a hitch support  180  may be affixed to the shank mount  176  of the accessory support  170 , and may include a shank  181  receivable by the vehicle hitch  18 . With this configuration, the hitch support  180  may mechanically connect the accessory support  170  to the vehicle trailer hitch  18 , thereby coupling the vehicle accessory hitch assembly  110 , and components thereof, to the vehicle trailer hitch  18 . 
     As discussed herein, the support members  190  of the first and second beams  130 ,  140  may include a plurality of slots  198  configured to accept a fastener, such as a bolt and nut fastener, that allow formation of a mechanical connection between the support members  190  and the first and second end plates  172 ,  174  of the accessory support  170 . The first and second end plates  172 ,  174  may include corresponding mounting holes configured to align with one or more of the slots  198  so that the mechanical connection may be formed. 
     The distance between the bed  20  of the vehicle  10  and the vehicle trailer hitch  18  may vary from application to application. For example, this distance for one make and model vehicle may be different from another make and model vehicle. Because this distance may vary, when the first and second elongate members  132 ,  142  and the first and second beams  130 ,  140  are coupled to the first and second base rails  14 ,  16 , the distance from the bed sections of this configuration to the vehicle trailer hitch  18  may also vary. 
     In an effort to achieve an adaptable vehicle accessory hitch capable of being adjusted for use with more than one vehicle make and model, the hitch support  180  may be mountable in a plurality of positions relative to the shank mount  176  of the accessory support  170 . The plurality of available positions for the hitch support  180  in conjunction with the accessory support  170  being mountable in a plurality of positions to the first and second beams  130 ,  140  may enable the accessory support  170  and the hitch support  180  to be positioned so that the shank  181  of the hitch support  180  may be aligned with and received by the vehicle trailer hitch  18 . The shank  181  may include a vehicle hitch pin hole  187  configured to align with a corresponding set of holes in the vehicle trailer hitch  18 , and to accept a hitch pin to secure the shank  181  within the vehicle trailer hitch  18 . To provide a plurality of mounting positions for the hitch support  180 , a mounting member  182  of the hitch support  180  may include a plurality of mounting holes  186 ,  188  capable of being aligned with one or more corresponding mounting holes  178  disposed in the shank mount  176  of the accessory support  170 . 
     It should be understood the plurality of mounting positions available for the accessory support  170  and the hitch support  180  may enable alignment of the shank  181  of the hitch support  180  to the vehicle trailer hitch  18 . It should also be understood that there may be several combinations of positions for the accessory support  170  and the hitch support  180  that achieve such alignment. In installing the accessory support  170  and the hitch support  180 , the ultimate position used may depend not only on alignment of the shank  181  with the vehicle trailer hitch  18 , but also, in some circumstances, may depend on a desired height of the accessory support  170  relative to the ground. For example, in installation, the type of accessory  30  being installed on the accessory support  170  may be known and have particular installation parameters, such as a required ground clearance or a specific mounting configuration. The accessory support  170  may be positioned to accommodate the installation parameters of the accessory  30  being installed. 
     In an effort to allow use of several different types of accessories  30 , accessory support  170  of the vehicle accessory hitch assembly  110  may include a plurality of accessory mounts  31 - 38  disposed at several locations on the accessory support  170 . The accessory mounts  31 - 38  may accommodate different connection configurations between an accessory  30  and the accessory support  170 . As a result, a first accessory having a first type of connection configuration may be connected to the accessory support  170 , and a second accessory having a second type of connection conversion may also be connected to the accessory support  170 . 
     The mechanical connection between the first and second elongate members  132 ,  142  and the first and second base rails  14 ,  16  according to one embodiment is shown in  FIGS. 3 ,  4 ,  5  and  18 . The connection members  134 ,  136  of the first elongate member  132  may be fastened via fasteners  156  to a coupler, such as the coupler  150  in the illustrated embodiment of  FIG. 18 . 
     The coupler  150  may include one or more coupler holes that accept a hitch pin  152 . The coupler  150  may be sized to fit within an aperture  17  of the first and second base rails  14 ,  16 . Once received, the hitch pin  152  may be slid through a corresponding hitch pin hole  15  of the first and second base rails  14 ,  16  and the coupler hole of the coupler  150 , thereby forming a mechanical connection between the first and second base rails  14 ,  16  and the respective coupler  150 . Several mechanical connections of this type may be achieved through the use of multiple couplers  150 , as depicted in the illustrated embodiment of  FIG. 3 . 
     In some circumstances, there may be multiple standard sizes for the hitch pin holes  15  of the first and second base rails  14 ,  16 . As a result, there is the possibility that the coupler hole of the coupler  150  may be undersized or oversized for the first and second base rails  14 ,  16  used in a particular configuration. To accommodate different sizes, the coupler  150  may be constructed with multiple coupler holes  154 ,  158  having different sized apertures at each end. Other than the different sized coupler holes  154 ,  158 , the coupler  150  may be generally symmetric. In this way, the coupler  150  according to one embodiment may be flipped or rotated, prior to fastening to the connection members  134 ,  136 , to accommodate the base rails to which the vehicle accessory hitch assembly  110  is being connected.
