Managing a dual alternator system

We have a two alternator 12V system, 1 for traction (capacity unsure) and one for leisure/house batteries (500Ah). For clarity this is a narrowboat fitted with a Nanni 43hp diesel. Both alternators are run off the crankshaft, via different pulleys.

Historically we have had battery charging issues and are considering a DC-DC connection (Orion) to allow the traction alternator output to be made available to the leisure batteries.

Does anybody have any dual alternator schematics? All the standard Victron offerings are for single alternator systems.

For completeness we are also considering solar panels with MPPT charge control.

Thanks

Anyone have thoughts on this? We are converting an ambulance which has dual Alternators…looking for the best option to charge a 270ah LiFePo4.
