Dual 6 volt batteries have their place in the RV community.
The advantage of dual 6 volt batteries is the ability to have a good amount of amp hours available for dry camping. 2-6's carry the advantage of having the capacity beyond dual group 24 batteries --- kinda like running 2 group 27 batteries, but two of those will not fit on my camper.
So if dry camping power is a priority, 2-6v's are worth considering.
