After reading these I love my Foretravel. I have been in sub zero many times. You just have to make sure the heat is on. I have aqua hot and good insulation. When it goes below zero I will help the AH out with some small space heaters underneath. You can also get a remote temp sensors so you know what is going on under there. We have had rallies in CO in the winter.
Here is a small heater and pretty cheap.

Sub zero in Virginia? Didn't think it got below freezing there. In WY we have closure gates. Nobody goes through. Sometimes for a whole week.
