Thanks Phill and Will, I agree as a cost issue, we just do mostly dry camping and I was just trying to make my propane last a little longer. Probably still negligible use, but a little here, a little there when you're dry camping and it adds up I think. I guess I would compare it to the whole trailer and why if you can close off some of it when heating or cooling to save energy just do it on a smaller scale. You're right though, I have to laugh when we spend $120k for a truck and trailer and then try to save 3 cents on something
