Abstract: A hinged vapor wall for use in mobile living quarters having a main living area and a secondary area such as a garage. The vapor wall has a first and second section that overlap to form a barrier between the garage and the main living area. When the sections of the vapor wall are in their closed position, the main living area and the garage area are divided into separate airtight compartments. Typically, small vehicles such as motorcycles and ATVs are placed in the garage, and the fumes from their fuel may spread into the main living space in the absence of a barrier. A permanent barrier sacrifices space within the main living area. The hinged vapor wall of this invention is movable to an open position when small vehicles are not being stored in the garage, enabling the garage to be used as living space as well.
