Used to be in the RV business in Florida. There was a trailer called a Park Model. Big living room, big bathroom, medium kitchen, small bedroom. Under 500 sq ft and HUD isn’t involved. On wheels and can move, screen rooms can be added. Wonderful seller especially for the retired snowbirds. Cheap and fast set up.

I have one set up at a lake near Raleigh. The carrying costs are almost nothing. It is very tempting to pack my suitcase, sell everything else and move.
