Greetings Leinhauser01,
I get along just fine either with RV resort power, or with generator power. A basic lead/acid battery system is very economical, and suits many folks just fine. The 2100 Bunk House is great and if I were to buy a trailer, is the one I would get. Just remember that without a sink next to the toilet, everybody is going to give you a dirty look every time you step out of the bathroom (ha-ha)
. A little RV humor there.
On a serious note, I know folks who install a bathroom mirror in the cabinet over the kitchen sink, and use that for a medicine cabinet.
Welcome to the forum.
