Not sure what the previous owner meant by "Arctic Package".

We spent 4-nights in Julian CA with lows of 15* and highs of 30* last winter. We had no problem staying warm with our "Mr Buddy" propane catalytic heater. We set the thermostat on the TM furnace to 65* and it came on for a few minutes. a couple of times in the early morning. We had no issues with the fresh water tank, grey water tank, toilet or plumbing.

One night, the wind got up to 30mph. We did have to fill some air gaps with folded paper towels (no big deal).

We put 'Pool noodles" on each side of the under side of the bed platform, where the bed slides are. There is a 2 to 3" space that benefits greatly with the pool noodles. We also have some of that "Reflex" insulation under our mattress to keep the cold from penetrating through the bed platform to the mattress.

NOW!!!! ........ Having said all that....... I would not recommend leaving the TM open in the snow. If you do, be very careful not to let the snow build up and develop a snow removal plan. TMs don't take kindly to snow-load when opened. In fact, they don't take kindly to heavy snow load at all.

Closing the roofs with snow on them is quite tricky.
