Chery, just to clarify ... it's my understanding (*) that the PD charge controller is only directly connected to the chassis batteries. It's the battery interruptor (BIM) that couples the two battery systems when charging voltage is detected (coach>13.3V) and needed (chassis <12.6V) or vice versa when driving, or when the dash switch is pressed.
* I just looked at an electrical schematic that may or may not apply to my rig or anyone else's.
