I have a 2015 T@b Outback that is parked in a carport in freezing temps with water in the tanks. I have it hooked up to shore power and the inside is warm enough, but I think the pipes may have frozen already as there's no water coming through the sink faucet or the toilet flush and the fresh water valve under the trailer is frozen in the closed position. Should I keep the Alde heater and/or the hot water heater running until I can get the camper to my service center to thaw out and winterize, hopefully before the pipes burst, or should I just turn everything off and hope for the best? Freezing temps are predicted for the remainder of the week. Thanks for any advice you can provide.
