Whats the coldest you've camped w/o problems

It got to about 25 in Cottonton, AZ area one time on us. The only problem we had were the water hose froze up. Just fill your tank the night before and leave the hose alone until it thaws out (moving it while frozen will make it break).....

We have camped where the temps have dropped to the mid to upper 20's and rising above freezing with sunrise. Much colder for any longer and real damage may occur, IMHO

Same as Ammandasgramma above. Just disconnect and stow the hose at night. Our tanks get heated by the forced air heater in the RV so they won't freeze.

-35 Celcius -31 F, we had electrical hookups only, but were using water and water heater.

This was constant for the three day's we were there.

But then again, we are odd and camp all winter long at those temps.

Camping in snowy environments. IM worried about ice and snow damaging the roof sealants and vents when towing.

Low 20's overnight, and low 40's during the day. This was over Thanksgiving last year.

You need to disconnect the city water and use from your onboard water tank, or you need to leave your water running overnight and a pretty decent stream, with your grey water valve open.

I disconnected from city water and brought hose inside. Went back out and hooked up next morning. Once the spigot unthawed. :-)

Early spring of last year, it dipped down to 16*F one night while we were camping. The campground folks came around and told us they were going to turned off the water in the early evening. I filled the TT fresh water tank, disconnected the water hose, had the heat on inside the TT and left the cabinet doors cracked by all the faucets and the water pump. I was paranoid still and woke up several times to run hot water at each faucet. Everything was ok.

We were in Big Bear, CA this weekend and it was in the mid twenties at night, we had no issues.

Living in a tent in central Alberta, hunting elk. Spent a week at around -35F. Using a propane radiant heater and a wood burning heater.

In the camper........-25C/-13F........and that was using all the water systems. Have done that temp in light weight outdoor camping as well.

In the rig in my signature, nothing really special done to it but it did take 3 electric ceramic heaters on low as well as the propane furnace to keep the rig around 23C/75F. It's an R7/R9 rig.
