Maybe I'm getting in late on this.....but in addition to opening the drain plugs mentions, I also drain the water heater and open the bypass valves. Then are you blowing out the water system with compressed air? That's what my wife and I do. It takes two. I handle the air and she opens the faucets, sharting in the kitchen. Finally we pour a little RV antifreeze down each drain. During the past two winters, we've had no problems...even with temperatures going below minus 20. We do not fill the water lines with RV antifreeze...on the recommendation of the Airstream Factory. Many dealers, including our closest Airstream one do recommend it though.
We usually head south in February. So I called the factory to ask about dewinterizing and filling the water tank before leaving here (Wyoming). The tech said the Safari is a four season trailer. Keep the furnace set on its lowest temp and the water system is safe to 0 degrees.
