I have the double burner Nuway stove in my Arctic Oven, it is very nice when,,,it isn't leaking,,,just returned from trip and the darn thing started leaking for the second time,,,I do carry a little spray bottle, to check for leaks when I set it up, and a co2 monitor. I had to resort to the backup Buddy heater from the boat the last day,,,it was a poor replacement. I like the adjustability and the incredible amount of heat it puts off, I was waterfowl hunting and got my clothing soaked a couple of times, I would fire it up on high, toss the wet stuff up in the attics,,half an hour later it is bone dry, I couldn't stay inside for the drying process, probably about 150 degrees in there, but would have dry gear for the afternoon hunt. I have a call in now to Nuway for repairs, if I can't get this fixed I may be forced into the wood stove option. In this wet/humid world wood can be a real pain though. I like to sleep very cold and the ability to stop/start the heat quickly is why I chose the propane option. I have used this NuWay up to 8000 feet and it worked great,,until it sprung a leak. Has anyone used the nuway at higher elevations than 8000?
