I love this heater for what it is. I use a boat tank for my fuel tank and leave it mounted on my jeep rack. It's way more then enough heater to pipe into two jeeps at once. I can run about 90 +- hours using 1&2 heat settings on 3 gallons of fuel. Best investment ever if you want your significant other to tag along on some overland trips. Definitely biggest down fall is the metric units on the thermostat and poor instructions but it wouldn't keep me from buying a few more.
