Well, there are different ways to connect them together; parallel and in series. You will want to connect them in series to make 12 volts.
I would think twice about whether you really need to go to two 6 volt batteries. I know all kinds of people swear by it, but we have never found the need. We have one 12 volt Group 30 Trojan that does us just fine; and we boondock for 2 to 3 weeks at a time. You are going to need a generator in that timeframe anyway. So that's what we do. And my wife loves to have 110 volts now and then for hairdryer, microwave, etc. And some people always are in electrical hookups, so there is no need to swap batteries in that scenario either. IMO, here is the only scenario for which it makes sense. You want to make sure you can boondock for 3 to 4 days and you don't want to run a generator or rules prohibit generators.
