T-125 (6v) vs T-1275 (12v)
Mex has been explaining the diffs between 12v and 6v deep cycle batts in recent threads, but there are still questions. With two of the 6s (66 lbs) that is 132 lbs for 240AH (20hr- 12a), while tw...

I did not go "All the way" with research but this is what I found
The T-1275 is a golf car battery, Just like the T-105, only 12 volt instead of Six, Used in among others the EZ-GO line of golf cars.
Thus it is a DEEP CYCLE battery. The only difference is the voltage and amp-hour capacity. I did not dig far enough to find the amp hour capacity.
Now; THERE ARE NO SIX VOLT BATTERIES IN RV's.. only 12 volt some of which are made up of two six volt batteries in series.
And so long as they are otherwise the same... And it appears the T-105 and T-1275 are. Number of cells and plate SIZE (not thickness) are the differeces) if you drop in say 450 amp hours of battery.. It matters not which way you get there. They are essentially identical save for amp hours.
Since both batteries are by the same manufacturer, the Amp Hour rating on the web page should be via the same method... So, that, and price, are the only things to compare.
Ok, Made another run at the specs.. T-105 230 amp hours, T-1275 150.
So, two T-1275 = more amp hours By the time you get to "Crossover" it's kind of .. Well... (30 T-105 and 23 T-1275 both have the same amp hour capacity)
looking at the trojan website a support material, one unanswered question is what is the cycle life curve for the T1275's vs. DOD??? I couldn't find any graphs that showed the T1275's. Graphs showed many other 12V and the 6V, including the renewable energy 12V.
I'm sure it exists, just couldn't find it. If they are comparable to GC it would be ideal, if comparable to other 12V, maybe not depending on your typical use.
