Yup, we had to quit doing our week-end driveway camps (here at home) for a while. Temps dropped between 12 and 32 for some time now. Running the propane and even supplementing with electric heat is costing to much now. So I unplugged the camper for a while and just have to enjoy the fireplace inside the house. Been though 4 tanks of propane since September. We're heading for Florida Christmas week, so decided to hold off the week-end camps until then. I suppose when we get back home, I'll keep her buttoned up until weather breaks and temps stay above 32 again. Then we'll go back to the week-end driveway camps! Yup! It takes a lot of propane to heat these babies in the winter!
