Constant power from a switch sounds like a good idea for that little fan that blows in to the tank valve area. I might investigate a highr CFM fan too. It looks like a big computer case fan.
That can make a big difference if camping with power and using an electric space heater which is how we survived the really cold temps we encountered last Nov.
I swapped the standard thermostat for a digital one with Heat/Cool and an Auto/On fan control. It was easy to wire the power wire for the basement fan so that it still comes on when the furnace kicks on but will also come on when the Fan switch is switched on. It stays on when the furnace runs. On our trip I think that little fan ran continuously for almost two weeks.
The electric space heater did a good job of keeping the camper warm enough. Although on the really cold days/nights we kept the slide in.
