Down here in Central Texas I winterize several times a year because we camp often during the "winter" our temps can vary from 80-90 one day to mid-teens the next. It's just too easy to blow out the lines and pour a gallon or so of antifreeze into the pee traps and toilet to risk the cost of lines freezing. In fact many times I winterize before leaving the campsite so that all I have to do is park the trailer when we get home. This works great for me because I usually have to be at work the next morning at 5am.
