If one was crazy enough to do so a wrap of insulation would do the trick.

There are plenty of full-timers north of the Mason-Dixon line. I have been told by a dealer that they sell a lot of DRVs to go to the ND oil fields. We are fortunate to have one of a very few brands of RVs that are engineered and certified for four-season use. I spent a winter in north-central WV. I have spent weeks in Milwaukee in the winter as well as other places. My coach(es) have seen temperatures ranging from 15 below zero to 130. I can tell you from experience that one of the things that are high on my list of things to avoid is a frozen black tank valve. I have had an electric water hose freeze before. Insulation is of extremely limited value if there is no source of heat.
