It does occasionally get a little cold here . In fact, this has been the coldest winter we've had in several years (probably 10 nights below freezing). It never went below freezing last year (global warming). Since the bus is in the garage, I just place a 75w bulb in the plumbing bay and run an 800w heater inside the coach on the nights when it is going to freeze.

I actually did the same thing in Yellowstone for 5 months with no problems. Everything seems to be very well insulated. Of course, in Yellowstone, we were living in the bus, and here in Pensacola, it never stays below freezing but a few hours at a time. I fully understand many hours of freezing would be disastrous. We have some on the forum who can attest to this!
