So here are my results:
Running my camper with fridge on LP and water heater on LP, I fired up this generator about 9pm. Running the A/C (Atwood Air Command with a MicroAir soft start kit) Overnight lows in the upper 70's with the thermostat set at 75, so it was a pretty good test. Ran the generator about 10 hours... until about 7 o'clock the next morning. I stopped for fuel that day and topped off the gennie tank ... it took 1.5 gallons. Fuel capacity is 3.4 gallons, so it easily could have run 20 hours on a tank of gas.
