We have had a class A and a class C after having a few trailers. Now moved to our 5er. I guess it depends on how you use your rig if one is better than another. We find we like to be able to us the TV to explore easier. We actually had a ranger give away our site once while we took the Class A out to see the area. He thought we had left... mid stay - what the heck. We started leaving chairs etc out after that. Anyway, we also like the added room of the 5er.
Now waiting on retirement
