Permanently living in a RV means, IMHO, following the weather, going south in the winter and north in the summer. I take it that you are not retired, just wanted some small place to live to try and save money. As Sprink-Fitter said: ?If you are going to live permenantly in a mobile home park, wouldn't it have been cheaper to buy a used mobile home an do all the skirting, and hard piping?"
With a 10x50 mobile home you would have a little more room, and something that is cheaper to heat and cool because of 6 inch walls vs. 2 inch walls.
