The correct way to wire them is to run cables between the terminals of the two banks, then take the positive power bus cable to one bank, and the negative cable to the other. Since the current from either (and both) banks goes through these wires, any voltage drop due to them is seen by both battery banks and they will charge and discharge at the same rate (or at least, at rates not influenced by the wiring).
This makes sense, but likely not going to happen in my setup - the second bank will be plugged in through an Anderson connector and be on the outside of the camper. Modifying the wiring in the way that it would hook up to the "remote" bank and be able to unplug it is probably possible but complicated.
