Abstract
A mobile rectangular base constituted by a motor home, trailer, or the like is overlain by a congruent cover. A foldable post is provided extending between each corner of the cover and the corresponding corner of the base so that when unfolded they rigidly support the cover well above the base. Walls constituted by a plurality of rigid panels can be pulled from the base or from the cover and slid along guides on the posts to enclose the structure. Hydraulic cylinders are provided to fold and unfold the posts so as to lower and raise the cover. When the walls are locked in place the entire assembly is rigid and self-supporting.
