I hope I can help out. We live in South Alabama, 40 miles from the Florida line. The beaches of Panama City, and Destin are 1-1/2 hours from here. Winter temps are mostly mild, In January the highs are in the upper 50s to low 60s. 70 degree highs are not uncommon. We do get a touch of winter though. When an Arctic front comes through, expect lows of around the upper teens to low 20's for a few nights. Snow is not common. Everyone gets excited when we see a few flakes. Last significant snowfall was the "Blizzard" of 2012 when we received 4". Before that was the "Blizzard" of '93 with 4" also. (Don't laugh, 4" shuts us down, there are no snow plows or salt trucks for 300 miles.) Because we enjoy winter camping, I do not winterize my RV. When I am not camping, I set the furnace thermostat to 40 degrees and it does not use too much propane. I think we used 3 bottles all winter.
