Your furnace is sealed. Their is no way wind can get to it.
My rv is not set up for winter use, I do not have heat in the wet compartment, Has anybody ever modify theirs to have heat down there. The last time I was cougth in very cold weather I placed an 1500 watts electric heather in the compartment where all the manual valves are, hopping it would do some good, after a while I got concern about the safety of doing this so I turned it off. did ok. I was parked at the time.
