That's excellent, you obviously know how take care of a battery. I've read many posts from people having had to replace a battery after 2 or 3 years.
I'm not in the the 2 x 6 volt camp

Yes it works. Yes you can gain capacity but often people compare apples to oranges like 2 small group 24 12v's against 2 6v. The 6v's probably weigh 20% more - so of course you'll have greater capacity.
I've rambled on about this before here:

Basically Ron, get the biggest, heaviest batteries that will fit. Deep cycle batteries are best, dual purpose would be a close second.
Here's a post detailing what I did when I replaced the single Exide battery with 2 Costco (Interstate at the time) group 27 size dual purpose batteries:

My battery capacity went from 95ah to 230ah.
In my current RV I installed three group 24 batteries in parallel (285ah in total). I had to go with group 24 size because that's the biggest that would fit in the trays. Again, I bought them from Costco.
