Adding More Batteries to My Class A - What gauge Wire?

Hi all, I've got a 30' Itasca Class A. It comes with (2) new 12 volt deep cycle batteries located under the doorway steps. I've build a new battery compartment which will hold (2) more batteries ...

It's actually 12' by the time you make the full run. Personally I would run 4/0 to keep the balance of the batteries as close as possible, otherwise your remote stack will never charge to the same level as the ORM location, nor will it share the same discharge load as the OEM. The only way to fix that is reduce the line loss between the two locations, especially since these are all new batteries.
But that's just me..
