Plus the chassis engine will be quieter than an normal Genset (my v10 is much quieter than the Onan 4000).

Sounds pretty good on paper. I guess time will tell.

If you add a second 330 Ah battery which I saw priced as low as ~ $600, it should be enough to power an A/C for a longer break of 2 hours. I’ll run the numbers using typical AGM specs when I get a chance.

Idling V6 gas engine for air conditioning could get tricky due to no-idling laws, but if you could do it, gas consumption wouldn’t be that much more than an Onan generator — at least not enough for me to worry about. A V6 should be less than about .5 GPH, so overall difference versus generator would be minimal during a 2-hour dinner break. Fuel cost, if any, would be less than a dollar, so not much compared to dinner bill.

Still, I’d rather have an additional battery or more rather than idle engine because I wouldn’t want to draw attention to motorhome.
