I'm from Davis County. Owned an Airstream since 2003. Never camped in the "winter", but was at Fish Lake on Memorial Day one year and 6" of snow full one night! Unless you have heated tanks I wouldn't venture out for the hard core winter camping, but October and November are real nice down south, say Zions. Less people, beautiful sunsets against the red rock...can't beat it! If you're questioning whether to get an Airstream vs. SOB trailer, hands down, Airstream. There's a crazy thread that's active out on the forums now about 'why Airstream'....check it out. Good luck in your decisions. If you want more info, let me know.
