Abstract: A trailer hitch which may be easily installed and removed from the bed of a pickup truck. The trailer hitch assembly includes a pair of retaining brackets which are mounted inside the individual wheel wells of the truck and are also secured to the truck frame. The retaining brackets each have a mounting aperture formed therein which cooperate with a pair of locking pins that are movably disposed at each end of a main support member that extends in use between the outside walls of the wheel wells in the bed of the pickup truck. The locking pins are spring-loaded and may be selectively actuated by a lever so as to render the main support member easily installable and removable from the bed of the truck. Centrally positioned on the main support member is a ball coupler for receiving the ball socket of a gooseneck type trailer hitch.
