It works well for us. They each (6V or 12V) have advantages and disadvantages, so everyone needs to decide which will work best for their situations and needs. In our case we have the ability to recharge because we have 2 Honda EU2000i generators with a parallel kit, so maximum use is not of prime concern. I just want to be able to go a few days without running the generators. I have two Trojan SCS225s in parallel which results in a 260AH 20-hour rating and 450 minutes @ 25 amp capacity, which allows me to go three to five days without recharging, depending on electrical usage/demands.
We frequently "dry camp/boondock" and resources/supplies can easily be 50+ miles away. If I went with 2 6-volts in series and one went bad, I am out of business. With 2 12-volts, I can isolate the bad one and operate on one, although at a reduced capacity. If I do need to replace one, 6-volts can be difficult to find in rural areas, but almost any small town with an auto parts store will have some type of 12-volt RV/Marine battery. It may not be exactly what I want, but it will get me back up and going. Also if the battery in my tow vehicle dies, 6-volts have no cranking amps available with which to jump start your vehicle. 12-volt RV/Marines can be used to jump start your vehicle.
12-volts in parallel are not the answer for everyone, but I believe they are the best for my situation. If I were going to dry camp for extended periods without the use of a generator, I might have decided otherwise.
I am just giving my thoughts and experiences for anyone considering what type of battery set-up to go with. Everyone will need to decide what is best for them. Happy Camping!
