Artic Fox 990 and winter camping

I did not realize it was going to get -32 below zero or I probably would not have gone there. weather forcast -16 below zero. I did put electric heater by basement fan so that probably helped. I was hooked up to shore power most of time so used electric heaters so propane was not an issue. I did notice a lot of cold air does come from where slide ends up when out. I will work on fixing that before next winter. also I would put RV antifreeze in grey and black tank to keep lines from freezing I worried about them. Make sure to order camper with bunk above dinette as a great place to put stuff. we could put all our snowmobile gear up there and still sit at table. we did not have any condensation problem.
