Hi KendalLP,
I mostly favor 12 volt--but in this case I'd do the four golf carts.
Just so you know two 6V Golf car batteries in series IS a 12 volt battery... (This is why I say there are no 6V batteries in RV's. they may be 6V on the store shelf. but when you put 'em in series they become a single 12 V
Specifically a 4D
The difference is the Golf Car batteries are designed for high capacity and slow discharge to a fairly low level. MARINE batteries even if they are marked MARINE/deep cycle or MARINE/rv, are designed to start a motor (high current draw but not for long) and be quicky recharged so they age faster if you run 'em down.
That's why I like GC batteries.. Want a 12 volt GC-12s do exist.
LiFePo4 is interesting but.. there are conditions where they are counter indicated.
