Not many posts here, I was gone camping with scouts all weekend, just got home.
For the future, it really depends in how cold you are talking. We have been out with the lows in the 20's with daytime highs around 40, in our 23B, with no issues.
I fill the exposed fw tank full, and use the fw tank. Cabinets that have plumbing that runs through them I keep the doors partially open to allow the heat better access to those areas. That's about all we do.
Water has a lot of thermal mass and it freezes from the top down. The tanks are very large and flat so any ice that might form, will not hurt the tank. If we go to the bathroom, we make sure to run a little water, just to clear the pickup tube. Again, we have never had any issurs.
We do use aftermarket mattress pad heaters, as the out side person, aka me, gets a little cool at night.
