70 above the 4 ft level, closer to 60 below the 4 ft level. This old RV is more than a bit drafty. It was -14 (I'm not talking wind chill) the other morning. I just got the furnace up and running a couple of weeks ago. The first time it has been turned on in probably about 20 years. I have been using a couple of small electric heaters. I am winterizing for the really cold nights to come. Insulated skirting, clear plastic over the windows and roof vents, insulation up under the front driver and passenger area. 68 is what I am shooting for when I get the drafts under control.
