If you are going to use an ACR then there is little point to a dual
charger because the ACR will see the charging voltage and combine the
batteries the whole time. Better off with a relay setup in the respect.

Here is where it gets tricky.  The charger runs one bank to the starter battery and the second bank to the auxiliary fuse panel for the house battery.  I plan to run the cable that currently goes from the charger to the starter battery to one side of the ACR and then from there to the starter battery.  The other side of the ACR goes to the same fuse panel connector as the house battery positive.
