My partner and I have settled on buying a used Class A pusher. There are literally hundreds available in various models and price ranges, yet, as newbies, we don't know what to be cautious about, what the pitfalls are. We want to live in this unit year round in temperatures that can fall to -40 degrees. I have been told that no unit can be lived in without problems with the water system at temperatures below -10 degrees.
Is it possible to find a unit that is equipped to do what we want it to do? Where can we get one if they are available?
