Some people may want to take advantage of the feature that allows the
batteries to combine even when the engine is not running, such as to
boost starting with the aux battery. That feature is of questionable
value for a Vanagon IMHO, and not required to be connected. No problem
doing it but best to increase the wire size if implemented. Increasing
the wire size makes for other problems so I say don't implement the
feature and keep things simple.
