A simple reasons for using 12 volt deep cycle batteries is I can have odd numbers of batteries but you can't using 6 volt batteries. Amps are amps no matter if you have 1 battery or 10 batteries. I tried the two 6 volt GC battery back in the 1980's and it never lasted before needing recharging any longer than having two 12 volt batteries of the same amp size in our RV's. 54 years of RV'ing for us. It's BS to me that two 6's are better than two 12's as again, amps available are amps available no matter whether two 6s or two 12's having the same amp capacity, period!
Next, if a 6 volt battery bites the dust, you will have no usable DC to use at all as 12 volts are required. 12 volt deep cycle batteries are off the shelf and available about anywhere but 6 volt GC batteries are much harder to find especially in low population areas as there is much less call for them. If one of the 12 volt battery fails, just simply unhook it's cable and you're stil good to go having 12 volts. Having either 6 volt or 12 volt flooded etc batteries you still follow the same rule of recharging when at 50% charge left. Who's kidding who???
I have repeadedly been getting 7 years + out of my 12 volt bvatteries. Why did I say +? Because my present 5th wheel 5 batteries were put in in 2010 and in just 3-1/2 months they will then have been in for 10 full years. Well, 4 of them will have been in for 10 years as one failed this summer so I took it out. Kind of became a game as I want to see if the other 4 will make it to 10 years.
Then I will replace all 5 at the same time. Not stuck with no DC anyway as I have the 2 that are in the wheel well and I have two 6' long #2ga fine strand welder wire cables (1 for + and 1 for-) that attach to the truck bed under the top rai junction block brass bolts with stainless wingnuts that go back to the 500 amp Marine barrel switch mounted under the 5th wheel overhang which then is connected to the 5th wheel battery input system in the cargo storage area where the inverter, converter, 12 volt fuse box, and the 5th wheel DC system connects to. The 5th wheel shore power cord is on the drivers side rear with the 110 volt fuse panel in an compartment accessed from inside the 5th wheel.
