Yes,
The Adventurewagon uses an isolator that reqiures a separate sense lead to the regulator. The alternator needs to have a tab cut and proivision made for this connection to the regultor. Personallly, i would tkae that isolator crap out and use stand alone combiner or controlled relay to handle charging of the house batteries. A good electrical guy should be able to sort this out.
