This is what I am speaking of Using the Van with the top up in colder
climates.. I am not worried about fiberglass top insulation as the loss is
nominal compared to the tent. I was thinking of using the aircraft
insulatino made to size of the tent to hang on the three sides to retain
heat..

But if you are thinking of using it in cold weather with the top up, then
you have a bigger problem than the fiberglass top.... the bigger problem for
loosing heat would be the tent.
