You have three 12s in effect. Wire the three 12s in parallel and put your load/charging wires on the outside batts. Not ideal for balancing but easiest. You can swap out the middle pair for an end pair every six months or every year to even things up over time as a way of balancing.
You have to separate the pairs for recharging to full at home before going to Float, but leave them as one big 12 for recharging while camping. The middle pair will not do quite the same as the outer pairs.
AGMs have to be recharged until they are accepting 0.5 amps /100AH at 14.4ish volts. You need an ammeter and voltmeter, and a charger that can hold its voltage at 14.4ish all the way down in amps as they taper. I use a Trimetric and an adjustable voltage converter/charger (PowerMax) to achieve that with my AGMs.
