Revcon Class A

The Dana 70 is chopped off on the ends. Axle half shafts use U-joints on the inners, and C-V joints on the outers. Photos on this page:

I see more GMC motorhomes in actual use, not often restored to vintage condition, just in usable condition. I suspect as a project, the GMC is less expensive, and there were more of them made to serve today as a supply of cannibalized parts.

You kind of answered your own question. There were about 12,000 GMCs built, and only about 2000 Revcons built, which makes a Revcon much more rare. As far as cost to work on, the older Revcon that was based on the Toro drivetrain was considerably lighter than the GMC, which meant a lot less stress on the drivetrain. The newer drivetrain, most parts can be bought at NAPA, once you know what you are looking for. As a project, it really depends which part of the project. GMCs often get all the interior cabinetry replaced, where a Revcon, there would be little reason to. The shell and frame integrity is stronger as well in the Revcon.
