2015 Elkridge 38 RSRT - Temps in the teens and wind chill is -2 right now. In our attempts to keep us and the RV warm, while staying here during this severe weather event, we installed window film to keep the cold out; however, that has created icing and condensation around the window frames. Also, although our RV is supposed to have underbelly heating, something has frozen, as we have no water; the pump runs but no water. We have a light inside the UDC but no idea where the freezing has taken place. We placed skirting around the north side and east/west end of the RV, which is where the wind is coming from. We'd read some on preparing for below freezing weather, but could not find anything regarding the windows. The timing of the severe weather, remote area and dangerous road conditions, kept us from obtaining additional skirting materials and other insulating materials to completely enclose and protect the underside. Any advice or ideas would be greatly appreciated!
