I'm a Southern Girl at heart; sweet tea and iced water run through my veins. Unfortunately Belle (my camper) is a bit southern too and defaults to frozen water with the tiniest little temperature drop. Since we're wintering in Washington this year, that's a problem.
Freezing weather creates special problems for RV water systems. Some campers have enclosed bay areas for water hookups. Some of those bay areas are even heated. I have neither heat nor enclosed bay. All of my water hookups hang right off the side of my camper. Exposed to all the elements. It's a winter wonderland nightmare.
