When I returned from Northern KY to SC 5 years ago I was living full time for work in mine and left it set at 55 degrees for the entire trip. No vents were blocked by the slides. I debated winterizing but knew I would not make the entire trip in a day and wanted to be able to use everything while overnighting.
I made the trip on February 3rd in between ice storms and the lows were in the teens.
I could not really tell much difference in the propane use, both tanks were full when I left and when I got to SC temps were mild, I did not re-fill until sometime in May.
