A lot of folks have commented about the dripping caused by propane heaters. Here in CO being so dry,and I kept the two vents open on the wall tent where the main beam goes thru on each end,I never seemed to have a problem.I used one of the 30K BTU Blue Flame from Northern Tool. Sure was nice not having to cut would and reach over in the Am to turn the heat on I also used it in my stock trailer when we made that into a camp.
