Can anyone give me advice or direct me to info on winter camping with an Airstream, How to, What not to do, etc. We live in Colorado, have a 25 ft Tradewind with a sketchy heater, its been winterized, but we are aching to head out and do some more camping. Are we totally crazy? or is it possible to use the toilet, hot water heater faucets etc. what's the trick to keeping it from freezing on the road?
