Abstract
A camper unit, adapted to be mounted on a vehicle, has a boxlike structure whose front, top and rear walls are formed in one piece of said foam plate sandwiched between aluminum layers with the angular junctions between these walls formed by mitering the hard foam and bending the outer aluminum layer so that edges of the hard foam plate are adhesively bonded together. The lateral walls are connected to the front, top and rear walls by connecting strips which are mitered at their ends to join one another all around the lateral walls and are welded to mitered junctions. A T-section member is affixed to the walls of the boxlike structure in a horizontal plane and circumferentially thereof to support the floor which is likewise formed as a hard foam plate sandwiched between layers.
