Yes, there is a reason that people get in their RVs and head south for the winter.
After you live in a snow state for years, winter somehow loses it's allure. I can remember having frost on the INSIDE walls of my home when it got down into the -25 or -30 ranges at night (Iowa). I could guesstimate how cold it was at night by how often the furnace cycled on and off. When the gap was 15 minutes or less I knew it was really, really, bad.
There's just no way I would want to stay in any kind of RV in a northern winter.
