One of the advantages of just using batteries in parallel to create a small bank is that it is easy to add one at a time.
There are a number of caveats that apply to any bank. Wiring to handle anticipated currents and to keep the current flow balanced between all batteries is one. Battery matching in age, type, and size is another. Neither of these is usually a significant concern in most RV situations as the currents are normally not that large and the batteries are usually the same chemistry and type.
As for the composition of the bank, keep in mind that total battery capacity is a matter of weight, not voltage. The service life is mostly a matter of how you use and maintain your batteries - again, not a function of voltage.
One of the biggest, unsupportable (so far as anything I have found to date) ideas is that there is something magical about 6v batteries. That's OK (I guess) if you are into 'feel good' purchasing decisions. I prefer a more empirical approach myself.
