2017 Sunseeker 3050S Winter Freeze Point?

[J. Frank]

If I keep some heat on in the coach, about how low of an overnight temperature can it tolerate without freezing the water lines. I live in North Alabama, and it appears that the first frost is still more than 2 weeks away, however, it is parked outside. I think we would like to take one more camping trip, and I hate to winterize until after that time. After crawling under it, it does appear that there are no exposed pipes underneath and it would appear the outside shower might be the most exposed and quickest to freeze?

Frost and freezing are two different things.

A good hard frost can happen without freeze issues.

And when it does freeze, things don't 'instantly' freeze the second it gets to 32º.

It takes hours for the mass of your R/V to get cold enough for things to start freezing solid. If you even have several hours overnight where temps get to freezing or below, you won't have issues as it will quickly ware above freezing. Now if it's going to be below 32º and stay there for several days... that is different.

Yes, the outside shower and low point drains are often the most susceptible to freezing.
