Airstream Trailering & freezing weather

[jbailey01]

I would like to travel in my 34' Excella during the cold months of the year in the mid section of the US. What would be recommended to avoid the unit freezing when I towed it from one site to another? I have thought of RV antifreeze in the on board water system and pumping it through before every move. This eliminates camping without a water hookup however. What have others done when traveling in cold weather?

If you have had heat on in the trailer prior to moving and the daytime temperatures will be above 25 degrees you should be able to move without draining the system.

For hard freezes below that I would suggest blowing out the system before moving and traveling with a dry system. If you trailer has a bypass valve on the hot water heater I would close it before blow down. The hot water heater will not freeze in one day of travel as it is too large a thermal mass.

The small amounts of water that will remain after a good blow down should not cause a problem with plastic pipe but could be a problem with the older copper pipe systems.

I would not use this system if you are going to travel more than the one daytime between campgrounds as the over night drop after a day on the road will present a problem
