Re: Freezing weather on return trip question
Water freezes as 32 degrees. There is no way around that. The only variables are volume and time. A large volume will take longer to freeze. The shorter the exposure time below 32 degrees, the less chance of freezing. Small volumes of confined water will freeze quicker than large volumes. I'd be more concerned about your small water lines than I would your water tank. Chances are that your tanks will not be full. If they are not full, then water has room to expand as it starts to freeze. Your water lines are pressurized and full. There is no room for expansion of freezing water. That could mean a burst. You don't tell us anything about your coach. Do you have an outside shower? Outside water faucet? Do you know anything about where your lines area run? How many are outside the body of your coach? Etc, Etc, Etc. All of that is necessary to know what your risk is. Driving through cold air with the wind blowing can be worse than sitting in a parking lot as well.
