we do a lot of winter camping in our slide in pop=up, while the onboard furnace is nice the propane creates a lot of moisture. We added a 3" port to the side of the camper and vented this heater to it. Problem solved, blows equally hot if not hotter, is much quieter and runs forever on a gallon of diesel....best part. No moisture. We've also tested this on our 30' toy hauler as well as my 2 car non heated garage...this thing just kicks. I also scooped it up for $110 bucks....no brainer. The control panel is a little hard to understand but we've figured out settings that work. If youre on the fence, just pull the trigger. Set up was super easy, less than 10 minutes to get this thing blowing hot air. I did add exhaust wrap just in case.
