ABSTRACT:
A coach, having an interior living space, which coach has at least one and no more than two expansion chambers. Each expansion chamber is formed as a box having top, side and bottom walls and one rear or front wall. The coach may be a trailer, an RV body disposed upon a truck chassis, or a recreational vehicle having a self-contained propulsion system. The coach may have instead of wheels as a support system, a series of vertical jacks or other support mechanism to thereby render the coach suitable for use as an office or an industrial facility. The coach features a spaced inner and outer wall construction and which may have no closing wall at the position at which the chamber is disposed. The chamber is adapted such that its sidewalls when in the retracted position are disposed between the inner and outer sidewalls of the living space. The expansion chamber sidewalls move from their respective first stowed inner disposition between the inner and outer wall rearwardly or forwardly depending upon the disposition of the expansion chamber to a second outer expanded position; and the top and bottom walls move from a stowed disposition beneath the top wall and beneath the floor of the living space respectively to a second outer expanded position. For support of the expanded chamber, a pair of deployable rails are moved from a stowed position to an in-use position, cantilevered from beneath the body of the living space to support the expansion chamber.
