Yeah, the bank of batteries is currently in series and produces over 110V. I bet my headlights would finally be bright - for a nanosecond  ;-)

My consumption should be low. A platinum-cat catalytic heater at times, but mostly just interior lights, stereo, etc for weekend trips. Maybe a laptop on an inverter. I think unless there are other disadvantages, the biggest one would be wiring it up and securing them. Nothing that a couple of hours with some wire and crimpers  and zip ties couldn't fix.
