It actually was a 1975 E-350 with a HUGE 460 engine.  Full conversion with wood paneling and blue shag carpet.  it went all over the country, literally.  Had little issues here or there, but was a solid vehicle.  I actually had this in college in Oregon and it was perfect.  I eventually outfitted it with off road tires and dual 4" side exit exhaust and it sounded like a nascar.  so much fun.  pile in 10 friends and go anywhere.  this one I miss too.
