There is normally an isolator or isolation relay that keeps the two systems independent when sitting at a campground. On the road this system will connect the batteries together so the alternator will charge them all. based on the year of your MH I would bet it has a red or blue battery isolator installed under the hood, attached to the firewall. If it is a relay it could be almost anywhere.
