If you were forced to run the 7.3L V8 solely to run a microwave or A/C, then yes, it would use more fuel.
However, when would you actually do that, and for how long? And how much of that would be offset by running A/C more efficiently while driving versus an Onan?
Think about it, if you stop for lunch and run a cold generator to power the microwave for a few minutes, is that more efficient than using batteries and inverter and then recharging while driving after lunch? I doubt it.
Anyway, I’m not worried about a gallon of fuel either way. I just like convenience, and stopping for lunch with full inverter power so I can run microwave, or make coffee, etc. by just turning the microwave on beats having to start a generator. I must be spoiled, because it’s not a big deal to crank a generator, but why do it if you don’t need to?
Do a search to see just how little most people actually use their Onan. And a lot of that is excersising the Onan which is a complete waste of fuel. Either way difference in fuel should be minimal unless you boondock frequently.
