Inverter generator while boondocking

We bought a Champion Dual Fuel 3,500 watt inverter generator for that exact purpose. We boondock about twice a year and the last time we did it BEFORE we bought the Champion, the on-board genset was putting out way more CO inside the rig than I was comfortable with, (measured by a calibrated CO meter...not just the CO detector). Even with a Gen-Turi installed, CO was higher inside than I wanted to go to sleep with. So, we bought the stand-alone unit and it works great! I can run one A/C unit and pretty much everything else. Have to make sure the electric water heater is turned off (can run either the A/C OR the water heater, but not both at the same time). It is more efficient with gasoline....1.2gal tank that will run it about 8 hours powering the A/C. On LP, it will burn a 20lb tank in about 10 hours under load and puts out slightly less power...about 3,100 watts instead of the 3,500 watts on gasoline.
