We have spent the last 2 cold winters up here in the NW, MANY days below freezing and lots of snow, I just put heat tape on the fresh water line ALL THE WAY to both ends then wrap foam sleeves on them and set the propane furnace at night to 65 and NO PROBLEMS! Walk in the park man,ALSO when you dump your tanks make sure you get All the waste water out of the hose or you will end up with a giant block of black ice in your hose next time you try to dump (Rookie mistake my first winter)
