If you can find TRUE deep cycle 12v batteries, they are an option but most you see at walmart or other non-specialty stores with the "deep cycle" label are not real deep cycle batteries but a cross between starting and deep cycle.
6v batteries are almost always deep cycle and easy to find as every golf course will burn thru dozens per year, so just about anywhere in the USA there is a market for them.
The net result is if you have a failure, it's far easier to find a replacement for 6v batteries.
Even TRUE 12V deep discharge seldom have the cycle life of a comparable GC. Look at trojan's spec's for cycle life vs. DOD for GC and 12V Deep discharge. GC still wins. Now, for many or most campers, the trojan 12V deep discharge will likely give plenty of cycle life. and they win for high current discharge.
However, it's much easier to find a GC battery somewhere than a true 12V deep discharge like the Trojans.
so, like so many things, each has advantages and disadvantages. pick and choose based on what is BEST suited for YOUR application.
