2 12 volt batterys or 2 6 volt
what gives me the most bang for my money. every other rig that I have bought always had 6 volt battery's but the new one has 2 12 volt. not sure what works better.

The 6-volter guys always bring up the "thicker plates" defense against the 12-volter guys.
Taken at face value this is seems to make sense, but it's actually a misleading defense. 6 volt batteries MUST HAVE and BETTER HAVE thicker plates if they're going to last as long as 12 volt batteries. That's because 6 volt batteries carry twice the current per cell as 12 volt batteries carry per cell.
The caveat in my statement above of course is "all other things being equal". The 6 volt versus 12 volt discussion is rarely comparing what it should be comparing ... 6 volt apples to 12 volt apples. For instance, what should be compared is 6 volt flooded deep cycle batteries to 12 volt flooded deep cycle batteries. :)
Battery life is an endless debate as there are too many variables.. Just because I get "X" amount of years out mine doesn't mean that you with your different usage will do the same... You will do better or worse,,,maybe by a lot.
But we don't need to have this debate. If you go to the Trojan website where they have done controlled testing of all of the types of batteries they make... They have the true unbiased answers there.
Trojan doesn't really care which type of battery you buy, just so long as it's one of theirs. So I believe what I read on their charts which lists all the batteries they make. And since this isn't rocket science, those same basic principles will apply to like batteries of other makes as well.
