Is there a DC battery charger in my coach?

Same setup used to maintain the chassis battery is used for the house battery. The difference is the addition of an isolator to keep the two systems seperated. When on either shore power or generator power your converter charger takes care of the house battery. If your sitting for a long time the chassis battery will need a dedicated battery charger to keep it up.

Thanks, I wasn't very clear on my original post but I was actually wondering about the house batteries, not the chassis battery (I've since edited the post to make this clearer). Do the house batteries get a full "absorption" charge when the alternator is running or does it adjust based upon the state of charge?
