My camper shanty is the one I was talking about increasing the size of the propane orifice in. I went from about 13,000 btu's to just about 24,000. It has always been warm enough, but it takes a long time to get the paneling warmed up inside. Normally I sleep with the window part way open to stay a little cooler. My son likes it warm so he sleeps in the other end. Hope to find out soon.
