Swope7896, I think that my first question would be ....how cold is cold? Determine your coldest expected temperatures and act accordingly.
Will you have water in the system,? If temperatures are quite cool for extended periods of time, will you have power to circulate heat to the tank/tank valve/waterline, plumbing areas. Power for forced air circulation is a non-issue if you are in a campground. If boondocking, do you have adequate battery capacity to run forced air without running the generator on a near constant basis?
For cold weather camping, there are quite a few things to consider and evaluate! memtb
