Am I the only one that has been down both roads,....and more than once ?
If you are an average dry camper like I am, (except we do winter at least 3 months off grid in AZ) you will not notice a dimes worth of difference in performance between 2 6'ers @ 230 AHs, and 2 group 27 12'ers @ 230 AHs. (2 group 24a......a whole nother story)
Amp hrs are amp hrs, no matter how you make them up.
As far as longevity, in my experience the 6'ers were very good. But I believe the 12'ers I have now, given the same care and maintence, will last a long time too. I can't go by the short lived 12'ers I had in the fixed voltage Magnatek days, because we murdered the batteries then, they didn't just die.
On the other hand, if you are a batt fanatic, and are one to babysit your batteries 18 hrs a day, and sleep w/ a hydrometer under your pillow so you can check SG twice before the sun comes up, then I don't know,....all bets are off.
But I promise you, a normal person won't notice any difference in performance tween 6 and 12v
