. I have never had a tank or water line freeze in the 12 years I have owned Bigfoots. But ---- you still have to keep the water system warm if you have water in it. If you run out of propane
or if the battery
runs out of juice they can and will freeze. You need to run the furnace
intermittently to warm the tanks and water lines. It blows heat down into the area where they are. Plus you need to run the hot water heater often enough to keep it from freezing. Just plugging in a space heater will not heat the hot water heater or the enclosed tanks and water lines. I regularly use my Bigfoot
at primitive (no electrical
hookups) camping sites during the fall
hunting season in Missouri. Temperatures are frequently in the teens at night. The single battery
will not run the furnace
blower all night. If you want to camp in cold weather without supplemental power you need two batteries AND some way to fully charge them every day. (Two batteries are very difficult to install in a Bigfoot
because of lack of space) My supplemental power in these situations is a portable generator
. When it is cold I usually run it in the evening until about 11:00pm. The battery
will then last until I get up the next morning. If it is really cold and miserable outside, and I don't want to go out and shut the generator
off, I will let it run until it runs out of gas.
The coldest night I ever spent was zero degrees Fahrenheit. That was at a campground in Williams, Arizona and I was plugged into shore power. I set the thermostat on low, left the hot water heater on and plugged in a small cube heater which I also set on low. It was perfectly warm and comfortable all night and the water system did not freeze. I took a shower the next morning. That experience eliminated my fears of cold weather camping.
