Well I'm pretty surprised by how warm caravans are. Stayed in mine last night, just had a small 2 bar electric heater running which we switched off when we went to bed, got down to -4 in the night, so cold that I couldn't get in the car in the morning because the doors were frozen shut, and I had to get the site owner to pull the caravan up the hill on the way out with his tractor because it was just a sheet of ice. Still quite warm when I got up in the morning about 7, still nice and dry too, but that's a small caravan with 2 in it, maybe body heat helps.
