Will Towing a Keystone TH to Alaska Make it Fall Apart?

I've camped in -15*F at Crater Lake as a ski patroller in my Citation pickup camper. With electric it did pretty well. It was 55* inside, but the double pane windows were lightly frosted over. I did have water on board, but the basement was being heated by a small electric heater.
While traveling the propane furnace did ok, but if the tanks got down below 1/2 there was less heat. At 30 below, I don't think the propane will be flowing very well at all.

The roads should be fine. Maybe smoother then in the summer.
