Yep. We love the out side kitchen, but we are at the lake most of the summer, and rarely use the inside.
Storage is kind of minamal and with 3 kids, I don't think I could full time in it, but 2600 sq feet (house) to 300 sq ft.... I guess that's camping- got to be "roughing it" somehow!!! As you said it could be a tent- I got enough of that in the Army.
