Also, might the recharge function be an issue with golf cart type batteries, given the existing battery management system on the Solera . Just raising a question here.
Plate thickness and surface area determines AH capacity.
Because there are only 3 cells in a six volt battery, they can have higher AH plates in the same footprint of battery. BUT YOU NEED TWO to get that AH capacity in a 12 volt system RV. Voltage doubles NOT AH.
A 12 volt battery has 6 cells so they have about 1/2 thickness of the plates and thus about 1/2 the AH capacity of a similar size and constructed 6 volt battery; BUT they are 12 volts and can be used "stand alone" if the companion battery gets damaged somehow. Two of them will give you similar AH as two 6 volt batteries of the same size and construction. Double the AH; NOT voltage.
The choice will be up to you. (You could also buy 6 2 volt batteries, etc)
Lots of good reading in the links I posted here House battery group number??
