Originally built by Interstate Battery for Rusty Wallace for $725,000. Later sold to Robin Williams. All stainless steel construction and rides smooth. Newer tires, new air bags, front rotors, brake pads, air chambers, and bearings. 4 Cruiseair ac units that need charged. 20kw 4 cylinder turbo diesel generator that was just rebuilt. 500hp detroit diesel engine that runs great. Would make a great project coach because of how well its built.
