I looked into changing my stock batteries last summer. I considered 6 volts as well as all the other 12 volt options. I ended up staying with the deep cycle 12 volt group 72s from Costco. My reasoning was everything in my camping set up is 12 volt already so if I had a battery failure I wouldn't be reduced to 6 volts. The other reason was the group 72 is easy to get, faily inexpensive and we have a Costco. Worked for me.
That is a complete myth.
There is NO advantage to using two 12V vs on pair of 6V..
All it takes is one cell to go bad in ONE battery and it will draw your "good" battery down and if not found quick enough it WILL dagame the "good" battery.
If you have one cell go bad in one of the 6V batteries you will not be running 6V, no it will be the SAME as if you had a 12V battery with one bad cell (about 11V). This will NOT interrupt your trip since most lighting will operate at lower voltages, your furnace may not like it but it won't ruin your trip any worse than finding a bad 12V battery.
As far as cost or ease of finding GC batts, Costco carries GC batts as well as Sams as well as Sears and many other places.
The advantage of GC batts is they are the MOST Ahr for the money... Most all other batteries simply will not give you as much Ahr for the cost and size.
So, if you are boondocking 6V GC batts should be a consideration, if you are not boondocking and have very little 12V usage without shore power then a low cost group24 Marine/RV battery will be fine.
