Hi gary,
Therefore you can only use two six volt jars. That is quite limiting from a capacity point of view. Better to go with an 8D AGM 12 volt.
I successfully use 12 volt jars in parallel. It matters how they are wired.

6 volts are the best to use for RV duty (wired in series). No battery performs at it's best wired in parallel with another matching battery because as they age, the difference in voltage between the two produces a constant current flow between them resulting in a constant charging situation as one discharges the other.
