I have a 2015 369RL which we keep on some property in West Texas and use it year round. The trailer is hooked up to a 250 gallon propane tank and I have two Interstate 12v batteries that are a couple of years old. We do not winterize the trailer since we use it year round and the furnace keeps things warm enough when set on 45 to keep everything from freezing.

This week was different and the power company was giving us about 30-45 minutes of power and shutting us off for four hours. This continued for several days while the temps were around 0 degrees. My water heater was left on propane. I assume the 45 min on and 4 hours off was not sufficient to keep the batteries up over the three days of power issues.

Assuming the power went off and the batteries ran down, would I expect the furnace to come back on after a power was restored, or will it stay off since the batteries ran down?

I will not be able to get out there to check things for another week and am just trying to be prepared.
