That would be a cool skoolie project for the right folks. Some people just love a restoration project and your bus will find a match.
That your rig gets about 10 MPG doesn't surprise me. Your Busette looks about six feet shorter than my 360 Dodge-powered Winnebago but weighs the same if not more. Wayne built tough skoolie bodies that just can't be executed in aluminum, Styrofoam and thin wood paneling. By contrast, you could smack the thick steel side of a school bus with a baseball bat and cause minimal damage - except to the baseball bat and your wrists.
Speaking of Wayne buses and people who love restoration projects, I actually found the owner of a big Wayne who likes my Winnie about as much as I like his bus. Go figure. We also have a lot of little PITA distractions that have gotten in the way of the actual trade. Hope I'm not jinxing things by posting this.
Wayne and Winnebago made strange bedfellows circa 1980: the latter provided chassis upon which Wayne built Transette shuttle buses. They looked like this:
I first saw them used as tour buses by the Coors Brewery in my hometown of Golden, Colo. Winnebago replaced the OEM front clip with one they made themselves so their mini motor homes would look different from other Chevy-based Class C's. (The mid 1970's Dodges only got a substitute grille.) This same design appeared on the bus chassis. I never figured out how the two different brands came together until I read this excerpt from
The Winnebago Story, (c) 1983 Winnebago Industries, Inc.: "Fabrication of special bus chassis for the Wayne Corporation, Richmond, Indiana. In 1980, the company built 200 units during the first year of a three-year contract." Suffice it to say that these "Waynnebagos" are hard to find today.
