Occasional Winter Camping??

If safe you might use the stove as a blue flame heater when you are not there. It would need to be done with no risks of spreading fire to the unit.

Of course, adequate propane would be needed, too.

Can you borrow a generator?

I suggest warming up, and then turn the temps down to 50 or so. In the AM, turn the heat back up to warm up. We lined our cabinets, windows, skylights/vents, and under our bed with Reflectix.

You can flush with RV antifreeze if needed.

I don’t think there is any reason to keep the heat running while you are out skiing. However, there are some ski areas that actually have RV hookups. In that case, buy a small electric heater.

A lot will depend on the actual temps when you go. I would not leave the furnace running when you are not there - you will run down your battery quickly due the the fan.

Lots of blankets for covers and picking your visits to nice winter weather and you should be fine.

There may be a fridge issue. Use it as an ice box instead of turning it on.

Very doable with precautions such as antifreeze in the water lines. Condensation is the “main” enemy but with short stays and drying out at home, you’re ok.

The tanks on a 8801 are inside so depending on how cold outside and how warm you keep the inside shouldn't be a problem. The windows and vent may drip condensation on you but for a night you could handle it. Make sure you have full propane to keep the heater going.

It shouldn't be a problem keeping the heater going. If it isn't safe I certainly wouldn't go to sleep with on. Not sure about what yours burns but you should have plenty of propane for a day or two and I would guess more.

If you don't want the hassle of worrying about freeze issues, go with it winterized. You will need to keep some heat inside to keep items in the cabinets from freezing.
