Abstract: A fifth-wheel hitch assembly is provided having a rotatable and slidable trailer hitch and a base with an arcuate guide along which the trailer hitch may slide rearward relative to the tow vehicle. A guide ramp directs the trailer hitch into one end of the arcuate guide depending on the relative motion of the tow vehicle to which the base is mounted. A capture mechanism is also provided on the trailer hitch which transfers rotational movement from the trailer to the base of the trailer hitch which, upon a minimum amount of travel, activates the guide ramp to guide the trailer hitch into the arcuate guide moving the trailer hitch head rearward relative to the initial position over the rear axle of the tow vehicle. The hitch assembly also provides for return travel of the trailer hitch head upon opposing rotational movement exerted on the trailer hitch head.
