Artic Fox 990 & winter camping

The only thing we have any issue with is condensation forming on the inside due to the airtight construction, just leave a window with a slight crack if you start to get buildup, if it is really cold maybe open the door under the sink a small crack to let warm in there, otherwise, there is nothing to do but enjoy.

Some people have electric heaters to run to save propane, if you do that though you risk freezing the pipes or tanks in the "basement".
