Looking for information on the hd 45 surplus heater, I am heating a GPsmall, and would like to use something more economical than diesel, ie gasoline and waste oil, but am unsure of settings or soot problems. The information that I have so far gotten indicates a 80/20 mix of wo/gas. Have you used one like this? Or suggestions. I also have the little diesel arctic heater, unsure of the nomenclature at this time, but it resembles the Yukon stove, just used it with offroad diesel the past weekend, but if it had been any colder, it probably would have been uncomfortable. Other than that it worked great.
