I have been looking at used Motorhomes on line and in person. I have always liked the Class C, but correct me if I'm wrong. I see lots of Class C's with Delamination, but I don't seem to find Class ...

IMHO, most delamination issues are from a lack of good maintenance, A or C-class.
I will disagree ! Delamination is caused by water, typically from the roof or around the windows) getting behind the fiberglass skin or soaking into the plywood sheathing (on aluminum sides RV).
I don't believe that an owner should have to apply layer after layer of expensive caulks/sealants for a rig to stay water tight IF IT IS DESIGNED AND MANUFACTURED CORRECTLY !
The typical EPDM roof fails around hole that come through the roof. At best, it has a life expectancy of 10 years (yes, you can get more if you regularly wash it and apply UV protectant or store under a roof).
TPO, especially commercial grade TPO, is more durable. Mounting things on the roof (A/C, vents. antennas, etc.) should be done on top of curbs made with pre-molded TPO corners and plastic welded to the rest of the roof.
