Possible to install W/D? Full timers. First RV.

So tell me the benefit of having a motorhome when the engine is going to be sitting there for months at a time. I have looked enough to know what a motorhome is, but not when you say "MH" Yes, we totally "dismissed" "MH" because I don't want to have to rely on the engine to have a place to live. Excuse me for not knowing that MH = motorhome. Having a MH, to me, seems like a lot of extra problems and more possibilities of that many more things able to tear up.
