I don't have a specific answer but it would obviously take 30 gal. a lot longer to freeze than a pet water dish. Also depends a lot on just how cold you need to prepare for. Upper 20's for a day I doubt would be a problem but from 20 on down it might be. Also, if you plan to actually use the water in real cold weather a lot more concerns than just the water tank freezing. It could freeze as it passes through the lines and pump and raise havoc. We have used an RV down to 7 degrees F. and the only thing that froze was the dump valves and water intake but we were using the RV and had it heated.
