摘要： An improved hitch assembly for a truck-trailer combination of the type using a pick-up truck wherein the hitch assembly includes a beam secured to a pair of spaced rigid, transverse members connected to the frame of the pick-up truck in a manner such that a hitch ball can be adjustably secured to the front end of the beam and forwardly of both of the rigid members. The hitch ball can then be connected to a vertical segment of a gooseneck tongue on the trailer. The ratio of the distance between the hitch ball and one of the transverse members and the distance between the two transverse members can be selected to assure proper load distribution between the front and rear wheels of the truck and to provide control of the forward movement of the truck when side loads are exerted on the trailer. An improved sleeper unit for attachment to the truck bed forwardly of the hitch is also disclosed.
