cold weather camping

In Cottonwood Arizona right now, yesterday was 25* overnight as well as I believ last night. where we are is about 5* colder than in town. we don't have an issue in cold weather other than we are wimps, we would rather have it warm. but anyhow, freezing isn't an issue with us, insides are warm and cozy at between 68* and 70* and no freezing pipes as all is contained in the enclosed underbelly. The only issue is that if you are hooked up, your supply hose could freeze. We always make sure we have full water tanks and extra water whenever and wherever we go. Good Luck & Be Safe ! ! !
