Dec 06, 2016I have had occasions in the spring and fall where the temps dropped below freezing and our trailer is not winterized. I set the furnace to 40 degrees, the lowest setting, and it has been fine. I do have it plugged in so a low battery wouldn't be a problem and if the forecast if below 25 then I would drain the system.
