We normally stay in campgrounds with full hookups and in the summer drive with the roof A/C on using the generator. The generator also runs the electric water heater and the refrigerator. I turn the them both on the night before we leave home while the PC is still plugged into the house. I turn them both off when we get back home. I only turn the gas on the water heater to test and clean it every now and then, It seems we don't need the gas part of the water heater to keep hot water. Since I am paying for the electric at the campsite, why burn my propane? If I dry camped, which is very rare, I guess I would have to use more propane.
