When to worry about WH freezing

[Chama]

We are back home in NM after a 2 month trip in our new E21 following pickup. At this time of year here, it is not unusual for temps at night to dip down into the low 30's for a few hours overnight. We have our trailer parked, connected to shore power and are heating the trailer to 65 degrees. I'm seeking opinions on whether the water heater tank or outside shower fittings are at any freeze risk with these circumstances. The water heater tank is not drained and we have the water heater turned off. Turn it on? Drain it? Or, just quit worrying? Any opinions?

I don't think you need to worry, but draining the water heater takes about a total of 3 minutes. Then 15 minutes to change your pants because the water shooting out got ya all wet!

If you turn it on for an hour it should remain warm enough for 24 hours.

That is confirmation your check valve is working!

(It only took me two dousing to figure out that opening a few faucets in advance would prevent getting hosed. My silver lining.)
