Why didn't batteries last longer
The batteries in my TT seem to have lost most of their capacity after three years. Now three years isn't terrible performance, and I was looking for an excuse to switch to 6 volt anyway, but I'm curio...

Batteries do age but 3 years if properly maintained is a bit fast.
your Deka Group 24s howver are not the best choice in RV batteries, You said only 65 AH each for a total of 130 Amp hours, roughly equal to a single Group 31
IF there is enough "Head room" (Height) then that same battery tray should hold a pair of 230 amp hour GC-2's. These are six volts each, but when wired in series (As opposed to parallel) they make 230 amp hours at 12 volts, that is dang near twice the capacity of what you have now. Same size, nearly the same price, Only modification you need do is toss one jumper (or double up on the jumpers between
You now have
-Battery+12 volt
-Battery+
You change to
-BAT+T-ERY+ 12 volt
One possible issue... I sometimes mention I once bought a new battery for my car,, LIFETIME guarantee. so long as I owned that car.
Did not last a week.. The replacement lasted.. Many years, and that one's replacement,,,, Well it went to the junk yard with the car after the car died of a drug overdose (Yes, the car died of a drug overdose, Shuttle truck from the drug store failed to stop in time and OVER-dosed (Ran over) the car)
Sometimes, you just get a bad one.
Deka however, is normally a good brand, I have 3 of them here, two GC-2 (House) and a Group 78 (Chassis)
