Hi All.
We have lived in some of the coldest stops in Americia. "Fairbanks Alaska", and "Central Oregon", and "Prineville Oregon.
It all breaks dowe to two things. #1. What kind of RV do you have. #2 And most of all, what have you done to your RV to make it so it can stay out in "Extream Weather Conditions".
There is a an alful lot you can do to any RV to make it much warmer than you think you can.
I lived in Prineville, Oregon, the coldest winter on record. We had a whole month or more of more then -40 to -45 "Below Zero". And the oldie but good Travel Trailer I used, didn't even have a real Furance. But rather one of the very old ones, with a Wall Mounted Radient Type Heaters. That and two 1500 watts Heaters on Mediumn.
I built a wall of the "Big Haw Bales" all the way around the entire RV, a 26 ft'er. I used some wood to hold the bales around the windows and stacked the straw Bales up to the roof line, And four foot High of rolls of R-22 Insulation, and covered with a very large tarp, so nothing could get wet. I also used two 100 watt Light Bulbs under the RV. It was still cold, but I managed to hang in therefor the entire winter. That winter I didn't have a choice.
We still do so serious Winter Time Boon_Docking. And our Motorhome is just a Basic Summer, and Fall and a Spring Motorhome.
Its all n how you fix up your Motorhome. We do just as well in the "Winter Time" as we do in the "Summer Time" After 46+ years as "Travlers" and "RV'ers, and most of all, "BOON-DOCKERS. You can pretty well handle anything. We even can very easlygo past our Motorhomes 30 AMP Service with no problems. We don't even bother to use the Motorhomes Furance either.
We have a Oly Wave #6 Propane Heater, with enough Low Pressure Hose to reach from one end of our Motorhome to the other end. Then we have a MR HEATER, "BUDDY" Propane Heater. Then we have a MR HEATER "BIG BUDDY" Propame Heater. I do keep our Motorhomes Furance in good running condition, for just in case of. The Motorhomes Furance is only a 25,000 BTU Furance. All of our Propane Heaters comes to 2,300 BTU'S
Trust us, we have the time of our lives. Good Luck. Happy Travels. Dan & Jill & our two Small "YORKIE KIDS who love to travel and Boon-Dock as much as we do.
