TB, Livin' in California, we never have had to worry much about winterizing our trailer, but I noticed that WW started offing the double walled water tanks last year. I didn't get them but I wounder if you did and what you think of them. It does get preatty cold out in the desert at night when we camp, but not cold enough to freeze 100 gallons of water. However, we have been some places in the summer that I would worry about if we were there in the winter.
