Danny, I own a 04 Winnebago Adventurer (gas coach) and all my tanks and storage compartments are heated. All I have to do is keep the propane tank full, I have a heat pump so it cuts out the electricity around 33* and the propane fuels the heat pump from there. Also don't let your gas tank get below 1/4 tank or you won't have fuel for your genset if needed. And of course when parked turn on your hot water heater. One time I had the electricity and propane to my coach turned off and it got down to 25* and my coach was just fine the next day!
