A trailer hitch or other auxiliary member is attached to the rear end of a vehicle (e.g. a cargo truck) in associated relation to a rear end lift, such that the hitch is free to move independently of the lift linkage when the lift is lowered for loading or unloading its deck, whereby the hitch may assume a noninterfering relation both to the ground surface and the lift linkage in such lowered position; whereas the movement of the lift to a stored position will automatically lock the hitch to the vehicle in rigid relation thereto such that it will properly function as a hitch when towing a trailer.
