I installed a Rugged Ridge 11214.53 Dual Battery Tray and 2 DieHard Advanced Gold AGM Batteries Model# 50733, one of them was 34R.
After much swearing and wishing I could punch something corporate, I got it to the original battery cables on 1 battery to start the jeep.
Using one of the batteries as an R designate lets me put both positive posts together.
This tray has a second piece that bolts on FROM INSIDE THE TRAY! So when I thought I had a bottom area of 10" to use, it was really only 9 3\4 due to the bolt heads.
So instead of returning the batteries or modding the main tray, I just eliminated the add-on piece.
Tomorrow I still need to sweat the new tinned lugs on to the 2/0 cables for my winch, and everything that connects to the 4 battery posts, and the 500A solenoid that connects the batteries together.
I need to make the connections, pull the winch electrical cables, install the Daystar KJ71044BK Black A-Pillar Switch Pod, run the wire from a switch to the solenoid and test.
