I'd combine all the T-105's into a single house bank, and connect ALL onboard charging sources to charge that bank.
Then, add a Group 31 starting battery -- flooded or AGM -- and an EchoCharge device to maintain that starting battery.
Unlike deep-cycle batteries, starting batteries are designed with thin plates to deliver a lot of amps quickly, for a relatively short time. This will make your engine very happy. And the EchoCharge will make the starting battery very happy.
