As I say most of the time when the discussion of batteries comes up, if you ask 10 people you will probably get 10 different reasons as to why they like 12 vs 6 volt batteries, true deep cycle vs hybrid, different mfr....
With new products coming on the market all the time the benefits between the 2 voltages (6 or 12) is shrinking. They have improved the 12 volt lines over the past few years and USBattery just released a new 145Ah 12Volt battery (no price yet). It used to be that the 12Volt deep cycle batteries lacked Ah unless you paid a ton of money... now they have started to drop in price. A benefit of a high Ah 12 volt battery is that it comes in one package and not 2. Some of the benefits people say is that if one of the 6 volt batteries goes bad, you do not have power. True, but I have yet to encounter a case where the battery just died, they usually do a slow death and it is noticeable (usually due to improper maintenance or age).
A lot of people think that they can just buy these expensive batteries and treat them like the inexpensive ones that come with the TT. You can, but most people do not perform proper maintenance on their batteries and start crying and moaning when they go south $$$$. I always recommend that people use the inexpensive batteries the first time around and get the learning curve out of the way, on inexpensive batteries...
I am still undecided as to what I will replace my existing 6 volt batteries with when they go in a few years (working on year 4 now). Already researching!!
For a little more battery information we have a "
RVing with SOLAR" social group that has a little more information on the difference in batteries, just page down to the 2 part posts.
Good luck,
