Abstract
A motor home trailer unit and a self-contained van unit are close-coupled together as one rigid unitary assembly. Full access is provided between the van and the motor home trailer when close-coupled together, and the van is readily detached for use as a self-contained separate vehicle for travelling, towing a boat or the like. Connection is made by a coupling arrangement including two spaced apart and forward projecting connector guide elements adjacent each side of the trailer unit at the bottom and the top of the front end wall thereof, and corresponding spaced apart connector receptacles adjacent each side of the van unit at the bottom and the top of the rear end wall thereof. The connector guide elements are detachably engaged and locked within the receptacles by corresponding movable locking elements when the units are coupled in a rigid unitary assembly.
