Dont count on that just yet Albert,
All your piping is inside with the exeption of your drain pipe,your holding tanks are too big to freeze in one night.
A few years ago i rode to Cali, at Flagstaff Arizona the temp was 10 below, i had icicles 2 feet long hanging out of my mirrors, no pipes or holding tanks frozen.
Now, if the temp was that cold and the rv was not heated on the inside that will be another story,,,
