Before you buy the best-insulated fifth-wheel trailer, do your homework. Dealerships are mostly trying to push their agendas, so you have to know exactly what you want. 

Not all insulations may be enough for below zero temperatures, so if you’re camping in such an icy tundra, make sure you understand what kind of insulation works. It never hurts to add more heating options on top of what comes with the RV. 

Also, keep in mind the weight of the RV and your own experience driving it around. It will be even tougher to move around in winters, especially when it snows or there’s a blizzard. If you’re new at this, make sure to master maneuvering it first.
