My class B is actually pretty trouble free.
When I first purchased it from an old gent it needed a lot of little things done, but once I've got those behind me I haven't had a problem in two years and use it often.
I want to be able to drive up to Montana sit out on the prairie for a month and go bird hunting. My B is a nice little RV but the "LITTLE" part gets on my nerves with 5 bird dogs ( they only come in during the drive up and then at night). I have a dog trailer for the daytime.
I like the idea of a A because they can ride inside and I can easily set up ( basically park) in a rest area on the way up.
Also I guess I just think class A's are cool and want one LOL.
