Lastly - As I keep telling people, Lead/Acid batteries do not play well in parallel. Even if you get two that came off the line one after the other, in parallel you will not see (capacity X 2). You can count on about 1.5 and 1.75 if you careful about charging, but more than that is dreaming....

Matt,
So, the common four 6v battery arrangement (which is both parallel and series) doesn’t have twice the capacity of two 6v batteries? Makes sense, but I’d never thought that. 1.5 is quite a reduction.
Edit (thought about this some more): Let’s say your batteries are rated for 200 amp/hrs. The first pair of 6v batteries will give you 200 amp/hr capacity (at 12v). Are you saying the 2’d pair will only increase capacity by 100 to 150 amp/hrs? What about the 6 and 8 battery setups; will the 3’d and 4'th pairs contribute even less incremental capacity?
