This is a great but for the money! I mounted it in my pickup for heating a rooftop tent. It pours out tons of heat with very little fuel and electricity overall. It would burn about a quarter gallon a night with the reading I have done so far. The electric pull is about 1.5 amps, so having a second battery is recommended, but not a hard requirement. I added a fuel filter and suspended the fuel pump to make it run even quieter. Would recommend for sure
