IMHO this is probably a bad idea if your planning to live in it next winter. Think of how bad it has been this winter and now imagine living in 300 SQ FT with insufficient heat, and no water part of the time. Get the picture. Any RV is very poorly insulated and older ones are probably worse than new ones. A motor home to be parked is just plane foolish. Motor homes are designed to be driven not parked. If you really want to try it, then get a TT. But don't expect to be comfortable if the temps get down to 20 or below.
