Got this to heat my 10x12 canvas tent for a recent hunting trip. First night was a learning experience as I did not have the fuel tank full and heater shut down at 2am and 8⁰f outside and 20⁰f in the tent. Lesson learned "fill the tank before bed".After that the next 6 nights went very well. Ran on medium setting and kept tent at about 60⁰f all night on about 3/4 tank of fuel.Instructions for this are terrible but there are tons of information on YouTube and Facebook groups to get past that. Ran it on a 55amp 12v battery with 100w solar panel to charge during the day
