I would think that our application is the exact opposite. Since we don't even use the 12v for starting, we hardly drain it at all. We use just a little bit of power from the battery initially for some electronics, and then recharge it.
Actually, what we might really need is some sort of NiMH or Lithium based 12v battery. Some technology that might be better suited for light draws and constant recharging?

I agree Walt, also I'm concerned a deep cycle may not be able to stabilize the voltage as good as higher CCA battery. If the DC/DC converter has times where it falls short to provide the steady amps needed to to run the heavy electrical loads, the system components could be damaged. We not only have electric motors for power steering, we have them for brakes, 2 coolant pumps, fuel pump, 2 battery fans, radiator fan, HVAC fan, seat adjustment, windows, wipers, lights, CD players, warning systems and safety systems. The Jump start system also needs a quick dump of the 12V battery battery and I'm just concern a deep cycle battery is not meant for our vehicle even though we don't have a 12V starter.
The car batteries are now offering much longer warranties and that's what shocked me with the OEM Motorcraft battery. My question was meant to ask should I go ahead and change my 12V battery when I have 6 months left on a full replacement warranty? The Tech was saying the battery is still good enough after draining it three times for the jump start procedure, but I should consider changing it. I think what he was saying was I can't get it replaced under warranty, but it needs to be replaced before it gets that bad. Also, has anyone replaced their 12V battery and was it covered under warranty?
