1977 GMC "Jimmy Mini"

Above article is the one I found but didn't link because it wasn't about "Mini." Even now, a Class C, even the 31/32-footers, are referred to as Mini Motor Homes in some circles.

This Jimmy could be a 454 V8 but I'd expect a 350 small block. There was also a "400" way back but I don't know if it was ever in vans and the WIKI article doesn't mention it. Transmission, a three-speed without locking torque converter or overdrive. Turbo Hydramatic, a "350" or "400." Those are transmission series names, not engine sizes. Still, typically the 350 was used with smaller engines and the 400 tended to go behind big blocks.

Very rugged engines and transmissions. Easy parts availability for the whole chassis.

Thanks guys.

Yeah what a cool history article huh? I read that some time ago. Wouldn't it be nice for all of our models to have such detailed reporting?

I call those GMC Class A's the "Stripes RV". I still love that show. :) But it is a different unit I'm talking about. The info I'm after is a Class C GMC van style front end with the basic house box on back. Many chassis are ordered (Ford, Dodge Chevy, etc.) and then the manufacturer builds on the Chassis. Winnebago, Coachmen, etc. But the box I'm looking at says "GMC" and "Jimmy Mini". Wondered who built that?

Wikipedia has an excellent article on the GMC Vandura (under the Chevrolet name) but doesn't speak much on the chassis-cab unit or larger than G20 unit. Even though it's a dually and a G30/3500, I expect it still has the same basic G20 engine and tranny options, but probably a different rear end.

Anybody with detailed info on that, appreciated.

But yeah, the GMC Class A, too cool huh? Everybody should read their suspension and drivetrain info.

GMC mini history

A gOOgle search turned up a writeup only on the fabled GMC Class A with Toronado front drive and tandem rear wheels. It DID show a couple pix of Class C's. The two I saw had the "Mini" labels showing, but the houses looked like they were made by different RV builders. Completely different cab-overs. One had the typical seamed front cap, the other had a molded fiberglass cap. I think siding material was different too.
Just shop it like any used RV. Chassis problems can get pricey but can also be dealt with. It'll likely need tires and brakes. If it has 16.5" wheels you might want to replace with 16". But if the body LEAKS, it's a loser.
