Camping trailer and automobile-trailer combination

A camping trailer is provided having a configuration to cooperatively combine with a towing automobile to integrate interior compartments and spaces of each into usable space. The trailer has a wheeled chassis provided with a forwardly extending tongue assembly and hitch assembly for interconnecting with the towing automobile and carrying a body structure having a front end portion configured to detachably interconnect with the rear end of the automobile. The front end portion has a front wall surface inclined upwardly in a forward direction to complement an opposed rear wall surface of the towing automobile and is provided with a flexible bellows that is detachably secured to the towing automobile around a rear hatch-type door of the automobile. An opening in the front wall surface of the trailer body structure permits opening of the rear hatch door of the automobile by swinging movement of the door through the opening and into the interior of the trailer thereby enabling combined use of the interior spaces. The hitch assembly is disposed at a longitudinally intermediate point of the trailer's inclined front wall surface to minimize the extent of relative swinging of the trailer portions adjacent the automobile. The top of the trailer body structure slopes upwardly in a rearward direction from the point of connection with the automobile to enhance aerodynamic efficiency while being towed. The top also incorporates a convertible construction to permit expanding the top from a lowered more aerodynamically efficient transport configuration to an expanded configuration provided greater interior head room and accessibility to interior components.
