Since I have normally been hiking in deep on foot for all of my Colorado Elk hunting I have been using a light weight 4-seasons tent along with a great sleeping bag and groundpad. I would love to be able to afford an outfitter tent complete with wood-burning stove and the horses/mules to go with it... but that's not happening (at least not yet). So I ask - is there a reliable and safe tent heater that will work flawlessly at 10,000+ feet? Everthing that I have read is that the run-of-the-mill heaters don't work in the thin air due to their low oxygen sensors. My real next step is to buy some hunting land and build a cabin on it... but that's not happening yet either so until then I would like to be warmer in my tent. Does anyone have a tent heater solution?
