This one is in the California Automobile Museum in Sacramento permanent collection. It has been for at least 5-6 years. It is a hand built, one of a kind RV built by an Air Force officer with several engineering degrees.
It is based on a 1971 Olds Toronado chassis and has OEM trim from Cadillac. The panels, glass and such was all hand fabricated. The drivers location feels very much like an aircraft cockpit. It was designed to fit in the mans garage and after he and his wife put over 100,000 miles on it touring the U.S.
