Adding my two cents about how much we like our Cook Partner. We went from a Camp Chief, that never really worked right to having the regulator blow in the middle of Idaho. Called them again and CC said they could ship me a replacement for $58 (I know right, to where?) so we nipped off to an outfitter that we found in Boise and we bought their display model (I also bought the repair kit). Two years later, 187 days of camping and not even a slight problem. It cooks on high, on low, in 40 mph gusts of wind in Utah, at nine degrees F, at 11,000 feet. It just flat out works.
I do have piped in gas on my trailer with a quick connect from a 20 lb propane bottle.
