Four seasons is a relative term. Depends on where you want to be during those four seasons. There are probably less than 3 or 4 real four season units. Big Horns are not among those. You can stay in any trailer if you run enough propane through it. In 15 degree weather you can go through a tank of propane in a day or two. It will still be drafty and the furnace will run most of the time. But then on the other hand, you will have a hard time finding a campground that has running water when it gets cold. The best answer is to go south in the Winter.
