ABSTRACT:
A leveling and support system for recreational vehicles operates on a plurality of telescoping air cylinders. Leveling is accomplished through a separate valve in the line for each cylinder, each valve being mounted adjacent the others, and adjacent an electrical switch which operates a DC motor in either a forward or a reverse direction. The motor actuates a rotary air compressor in a forward or reverse direction for changing the air pressure from positive to negative while operating each of the valves to each cylinder line.
