I just had to share how proud I am of our Airstream. We took her up for a few days of skiing during which time the temps in the evening dipped down to 2 degrees. Our Airstream has a feature that when the furnace is blowing air into the cabin, it also diverts some of that air onto our pipes so they do not freeze. We also had our hot water tank on for extra precaution against freezing.
There were a number of Arctic Fox RV's who experienced some major problems with freezing and they are built for this type of weather. We loaned our generator to a few neighbors so they could get their RV's fixed.
Anyhow, I just wanted to share how happy we are to be Airstream owners. Our experience as Airstream owners has been nothing but positive so far (given a few leaks here and there which have now been fixed, thanks to help from fellow streamers on this great forum).
