After having read blogs and websites about skiing in the motorhome, it seems a few advocate wearing lots of layers and wearing hats in bed at night! We have never felt the need to! We even sleep with a window open to keep condensation at bay. We have a normal duvet on the bed and when we are up, it is feet in socks and T-shirts. We keep the heating at a constant 20-22 degrees. Are we alone in the level of comfort we expect from our van in Alpine conditions?
