Battery wire question

The primary battery that my converter hooks to is under the step to the bed in front t of our truck camper. I have a second battery at the back of the camper about 8 feet from the front battery. The dealer ran 6 gauge wire between the two batteries. Is 6 gauge sufficient or is it worth the cost to run 4 gauge wire? The batteries usually don't get used too much. Just an occasional day or two at most.

    Ideally, batteries shold be "balanced" - loads (or alternator) should use Pos from one battery, and Neg - from another one.

    If they dropped each Neg directly to the frame - I don't know how to balance them, other than running a separate #6 Neg wire from the farthest battery to loads/alternator. Maybe braniacs here will suggest something better ;)
