More money doesn't guarantee better quality. There are several "fulltime" rvs that are constantly on the forums with build problems.
I find that most of the money is on cosmetics such as solid wood cabinets, granite counter tops, tile floors, all the bells and whistles that eventually go wrong as they are part of a major harness that you cannot get to for repairs.
Maintenance is the key, find something with a good floorplan at a reasonable price. Remember, most who start out fulltime quit not soon after and that is one reason why used rvs are cheap.
