New to RV's and need some advice for winter....

don't seal it up too tight or you will end up with another set of problems. You need some fresh air in that tight of an area. I don't know how you will keep that thing warm up there unless you build a roof and walls around it, then insulate it. You might find someone with a pole building or a barn for cover, at least it will keep the wind of you coach, you might have a chance then.Supposed to be another bad winter again, (maybe)
