Hi,
No increase in wire size is required so long as the new distance from the bank to the converter is shorter than the OEM distance.
If upgrading the converter--then the new install would need larger wire to reflect that change.
I would make a sealed box that is vented outside in case of catastrophic failure of the AGM batterys.
Make sure the converter will support AGM chemistry.
On the outside of the sealed box, leave space for a nice sized inverter. It is so lovely to have lots of 120 volt watts to use as needed.

If the existing wire from the single coach battery to the converter/charger is a particular gauge, then by adding one or more batteries will it need to increase in size?
