Sitting in MĂ©ribel 0840 and the outside tempature in -8. This is the first time we felt the van cool showing 13 at about 0700. I have a selection of 4 electric heaters depending on the campsite ampage.We have 10 amps here so not a lot of wriggle room. I leave the blinds open over the day to try and catch a bit of sun. Most of the cold air is coming from the cab that I have blocked off with a blanket. Dread to think the tempature with wind chill once we start skiing. When parking the van slid to within 2 inches of a wall so had to put on chains to move away. At least the sun is shining
