A trailer hitch that provides a heavy duty center box type for gooseneck or fifth-wheel trailers which may be quickly removed from a truck bed to leave the truck bed uncluttered and unobstructed. The hitch includes a hitch frame that fixedly mounts rear latch legs to depend therefrom through slots in the bed to latchingly engage the rear edge portion of a mounting member which is fixed to the truck frame beneath the truck bed (floor). A pair of front latch legs are pivoted to the hitch frame in depending relationship for movement by a handle between a position to latchingly engage the front edge portion of the mounting member and a release position. Lock arms are mounted on the hitch frame for pivotal movement by trigger mechanism between a position to retain the front latch legs in their latching position and a position permitting the front latch legs to move to their release position. The trigger mechanism is resiliently retained in a position that the lock arms hold the front latches in their latching position. A hitch ball extends above the hitch frame.
