ABSTRACT:
A structure having an interior living space, an optional cab for operation of a propulsion system, and at least one expanding chamber. Each chamber is a box with one open wall. The structure may be a towable trailer, a recreational vehicle body on a truck chassis, or a motorized recreational vehicle, or a trailer with a support system instead of wheels for stationary use, or a fixed building on a foundation. The structure's living space is open at the interface with a respective expansion chamber. For use, a stowed chamber moves from within the structure, between its outer walls, to an expanded position external of the structure. A pair of cantilevered deployable rails are moved, prior in time to a chamber exodus, outwardly from beneath the structure to support the chamber to be expanded.
