A winch assembly for moving a first fifth wheel outwardly from a first trailer and engaging a king pin on a second trailer. The winch assembly includes a pair of parallel, spaced apart rails mounted on the underside of the first trailer. A slide out frame is mounted between the rails and attached to a front axle and a real axle, with wheels. The slide out frame includes the first fifth wheel adapted for engaging the king pin on the front of a second trailer. The first fifth wheel is attached to a pair of first cables on winch drums, driven by winch motors. The winch motors are used for rotating cable drums for retracting the first fifth wheel along a length of the trailer. Also, a pair of second cables on winch drums, driven by winch motors, are attached to the slide out frame. The second cables are used to extend the first fifth wheel outwardly from the rear of the first trailer for engaging the fifth wheel to the second trailer.

The disclosed apparatus, systems and methods relate to an improved fifth-wheel hitch which features a pivotally-mounted head assembly. The hitch assembly has a rocker assembly which allows for the pivotal movement of the head during mounting. The rocker can be secured in a fixed position during transport. A multi-point jaw assembly is also provided. A rail kit adaptor and gooseneck adaptor are also provided. The assembly is light and engineered for quick and efficient installation and use in the bed of a truck.

A fifth wheel hitch adjustment arrangement for adjusting a position of a fifth wheel hitch plate along a length of a vehicle frame, the fifth wheel hitch adjustment arrangement including a fifth wheel hitch plate, a support arrangement coupled to the fifth wheel hitch plate such that the fifth wheel hitch plate can be moved between a first position along a length of a vehicle frame and a second position along the length of the vehicle frame that is different than the first position, and a drive assembly adapted to couple to a vehicle frame and coupled to the support arrangement, the drive assembly including a rack-and-pinion arrangement, the rack-and-pinion arrangement including a rack member engaging at least one pinion member, the at least one pinion member engaging the rack member of the support arrangement to move the fifth wheel hitch plate between the first and second positions.

A vehicle accessory mounting assembly for mounting a vehicle accessory to a vehicle fame assembly includes first and second support members adapted to couple to the frame assembly, a support assembly that includes first and second portions respectively slidably positionable along a length of the first and second support members and selectively engaging the first and second support members to lock the first and second portions at a selected position along the length of the first and second support members, a center portion having first and second portions, wherein the first and second ends of the center portion are adapted to couple with the first and second portions subsequent to the first and second portions being positioned along the length of the first and second portions, and a vehicle accessory arrangement coupled to the support assembly.

A fifth wheel coupling device is adapted for a towing vehicle that vertically receives a kingpin of a trailer. The device includes a plate having a kingpin hole formed therethrough defining a vertical path adapted to permit entry of the kingpin into the kingpin hole and through the plate along the vertical path, and to prevent release of the kingpin out of the kingpin hole along a lateral path leading outside the plate. A support base is attached to the plate, and is adapted to mount the plate to the towing vehicle. A lifting mechanism is operatively connected to the plate and is adapted to be mounted on the towing vehicle for raising and lowering the plate relative to the trailer. A locking mechanism is movably attached to the plate and is provided with an actuating portion. The locking mechanism is configured to be automatically actuable and adapted for releasably locking the kingpin relative to the plate and the locking mechanism upon engagement of the kingpin with the actuating portion of the locking mechanism.

A fifth wheel hitch adjustment arrangement for adjusting a position of a fifth wheel hitch plate along a length of a vehicle frame, the fifth wheel hitch adjustment arrangement including a fifth wheel hitch plate, a support arrangement coupled to the fifth wheel hitch plate such that the fifth wheel hitch plate can be moved between a first position along a length of a vehicle frame and a second position along the length of the vehicle frame that is different than the first position, and a drive assembly adapted to couple to a vehicle frame and coupled to the support arrangement, the drive assembly including a rack-and-pinion arrangement, the rack-and-pinion arrangement including a rack member engaging at least one pinion member, the at least one pinion member engaging the rack member of the support arrangement to move the fifth wheel hitch plate between the first and second positions.

A fifth wheel mounting assembly comprises first and second support members adapted to couple to frame members and support assembly that comprises first and second portions slidably engaging the first and second support members and adjustable along a length thereof, the first and second portions including an upwardly-opening recess, first and second mounting members coupled to the first and second portions and configured to pivotably support the fifth wheel hitch plate, and a center portion having a first and second end received within the recesses of the first and second portions, wherein the recesses of the first and second portions are configured to receive the ends of the center portion subsequent to the first mounting member being coupled to the first mounting portion and the second mounting member being coupled to the second mounting portion.

A method for increasing the aerodynamic efficiency of a vehicle includes monitoring operating condition of a vehicle, determining if a pre-selected event has occurred with respect to the operating condition of the vehicle, communicating a spacing value to a moving device and adjusting a spacing between a cab and a trailer of the vehicle based on the communicated spacing value.

A fifth wheel hitch is shown and described. The fifth wheel hitch may include a base frame configured to be secured to a load bed of a towing vehicle, a trolley operatively engaged with the base frame, the trolley adapted to move along the base frame between first and second positions, and a cam member attached with the base frame, the cam member having a cam path. The fifth wheel hitch may also include a cam follower coupled with the trolley, the cam follower operatively engaged with the cam path, and a fifth wheel head pivotally coupled with the trolley, where the trolley is moved between the first and second positions in response to pivoting of the fifth wheel head.
