It's George Barris' "Super Van" based on a 1966 Dodge Tradesman. It was lengthened, the body removed for a completely custom replacement and after extensive alterations from front to back, Supervan emerged from Barris Kustom industries in its first incarnation as the Love Machine.
Initially it was painted yellow with orange shag and interior appointments that included a revolving bed and an entertainment console. Later it was re painted to Day-Glo pink but retained the orange interior.
Super Van was the title character in Super Van, the Movie in which the Van was a Futuristic Solar Powered vehicle, coveted by bad guys and protected by the Good Guys.
The Van toured Hot Rod Shows and special events all over North America for several years and a model kit was produced of the Love Machine by MPC.
After that, it was reworked again and appeared in Back to the Future II as the Hill Valley Transporter.
