Yes, most motorhomes are totally electric with heat and cooking being the typical exceptions. My coach is has diesel heat for an alternative to electric heated water and interior heat. I have 6 8D house batteries, so I don't have to run the generator unless I want air conditioning. If I need or want to run the air, I'll look for a CG. My generator is extremely quiet, but I don't like running over night.
Most dry camping events, like NASCAR races or the Alberqurque Ballon Frst, have generator quiet hours. Given you didn't pay anything to stay at a WM, truck stop, or rest stop, you get what you pay for. I suppose you could just move.
