I prefer 2 12 volt batteries. Two sixes may put out a little more, but if you are out in the boonies and one battery quits and it is a 6 volt you are up the creek. But if it's 2-12s you can disconnect it and get by on one.
Our last mh we replaced the 12's once in 13 years, and they were still good when we traded it.

I'm not following you. So you are saying that true deep cycle sixes are prone to fail sooner than a dual purpose? Running two 12's is preferred in case of failure yet they lasted 13 plus years? Doesn't seem like building around potential failure is worthwhile. Getting the advantage of true deep cycles seems worthwhile. Am I looking at it wrong? I can get 630 ah of sixes into a space that that I can only get 400 ah of 12's.
What he is saying is that if you have a 12V battery you can run your RV. If you have two 12V and one fails you can run your RV off the remaining one. If you have two 6V and one fails you are up the creek without enough power :-) A lot of people that run 6V run 4 so you can always disconnect two batteries and still run the RV.
