Welcome to NuRVers! Congrats on starting out in such a difficult winter. If you can handle this, the rest is going to be super easy!!
I was in Colorado for Nov, Dec, and Jan this year. We didn't get the snow you guys are getting, but it was pretty damned cold. I had a 20A electrical connection, and went through a lot of propane. Just do whatever you can to keep yourselves warm, and to keep the vitals of your home from freezing. I got a couple of remote thermometers that really helped. I would check the temp of the wet bay/tank area to make sure it was staying above freezing. Had no (big) problems :)
Welcome to the road. Wishing you thawing weather soon!!
