Paragon,
I personally agree that that's the way to go.

I was just trying to answer what I thought was necessary if Jesse really wanted to run he stereo off of the second (deep-cycle) battery. I think he wants to beable to crank up the stereo and run the dish+TV on the second battery possibly draining it, then when he's ready to go home, expect the primary battery to start and power the entire car.

But it makes just as much sense, or more, to swap the primary battery with two hybrids, run everything off of the primary batter, and keep a second hybrid completely isolated from discharge except when wanting to start. This is the brain-dead approach. You don't have worry about accidentally draining both batteries.

Trying to wire just the inverter and stereo to one battery and running everything else off of the other battery is, in my opinion, a more complicated way to achieve a similar ends provided Jesse uses the system the way Jesse says he will and doesn't accidentally run something off of the main battery at the same time.
