Got some very interesting info from a guy at our dealership who does a lot of winter camping. He really can't get away during the camping season, since he's always working, so he does his camping in winter - in Wisconsin. He said if you're going to fill up your freshwater tank - fill it FULL. Takes longer for water to freeze when there is that much volume. The heating pads on the tanks are barely above "adequate." They're small, and they work on 12-volt only. If you want to use your toilet, instead of using water, use the windshield washer fluid that is treated with antifreeze. You could also use the pink RV antifreeze, but that could get "slushy." The windshield washer fluid will not.
