Greg:
Not what you have, but close...
Last year a HO that had the utility cut his power for non-pay & theft, had an older Infiniti idling in the driveway, jumper cables to three additional 12 volt batts, and cobbled to two inverters. He ran his furnace and his PC!

I was there on a complaint call from the FD. Me thinks the guy could have used a 5KW gen for the same gas the Infiniti burned.
