A gooseneck hitch assembly for attaching to a tow vehicle such as a pickup truck. The hitch assembly may include a cylinder attached to the vehicle frame such that the cylinder extends through the vehicle cargo bed. A ball hitch may be removably inserted in the cylinder and may include a pair of slots for receiving projections in the interior of the cylinder. A locking member may be positioned on an upper portion of the ball hitch to secure the ball hitch to the cylinder and to provide a visual indication of the locked condition of the ball hitch. Grooves may be formed in the ball hitch to receive the cylinder projections so that the ball hitch may be stored in the cylinder in an inverted position. In the stored position, the bottom of the ball hitch may be flush with the top of the cylinder to prevent the ball hitch from obstructing the cargo bed.

A pivotal pin lock presented as an improvement to a fifth wheel hitch receiving a kingpin from a fifth wheel trailer, said fifth wheel hitch having an opening, two side plates, and a kingpin locking mechanism, said pivotal pin lock adapted to pivotally engage said side plates within said opening of said fifth wheel hitch, said pivotal pin lock comprising: a ramp plate having a weighted ramp end, a locking end, an upper surface and a lower surface; and a transverse pivoting rod attached to said lower surface of said ramp plate, said transverse pivoting rod further forming two extending pivot arms, said pivot arms pivotally engaging said side plates in said opening of said fifth wheel hitch, said locking end of said ramp plate directed towards said kingpin locking mechanism of said fifth wheel hitch, said ramp end presented lower within said opening of said fifth wheel hitch than said locking end, said locking end blocking release of said kingpin in said opening once said kingpin has passed over said upper surface of said ramp plate in said opening. 2. The pivotal pin lock as disclosed in claim 1 wherein: said kingpin makes first contact with a tapered edge of said ramp end of said ramp plate upon said upper surface, said kingpin continuing over said upper surface until said kingpin moves onto said locking end, said kingpin tipping said ramp plate, pivotally lowering said locking end and raising said ramp end, said kingpin passing said locking end of said ramp plate, depositing said kingpin into said kingpin locking mechanism of said fifth wheel hitch, said ramp plate pivotally returning to where said ramp end is again lower than said locking end, said locking end blocking said kingpin from being removed from said opening past said ramp plate unless said kingpin is raised out of said opening. 3. The pivotal pin lock, as disclosed in claim 1 wherein said pivot arms are pivotally engaged with said side plates in said opening of said fifth wheel hitch by the process of: boring aligned holes in each said side plate; and inserting each said pivot arm within said hole in each said side plate, allowing said transverse pivoting rod attached to said ramp plate to pivot freely within said opening.
