They are wet 6 volts that came with the coach. I've thought about changing them out for two 12's in a series but some battery gurus here say it wouldn't make much difference. As long as the inverter kicks out at a given voltage, the fridge will never be harmed.

Two 12's in a series would give you 24 volts--don't want that (or 0 if you hook them up backwards but that will also give you busted batteries
). You want the 12's in parallel.
Your 6's are in series.
