Year round in a class C?

It can be done. I spent about 30 nights in my class C RV last year. And some of those nights were very cold. Most RV's in general are not well insulated so when it's real hot or real cold, your AC or heater will have a tough time keeping up. You can do some things like use a lot of Reflectix, possibly insulate the walls or even add one or 2 space heaters. As for the wood stove I would be afraid of fires of weight issues.

After about a week in my RV I am looking forward to my home shower and my home bed.
