Not sure on the GMC motor homes, but I know where a couple are sitting and I'll check the VINs. Incidently I looked at one over the shutdown which was listed as a '79.
Both Flint and Pontiac built heavy duty trucks as of late. I'll take an assignment and try to define that through the model years. It may be too complex (due to the high level of model proliferation/permutations) to fit on your chart. Truck guys are used to that kind of thing.
