Not a Sprinter expert, so I will defer to more knowledgeable folks on your chassis, but just a few comments while we wait for them......
I don’t believe the Sprinter charge system allows for charging coach batteries from the alternator (unless something has changed that); the generator and hydraulic leveller system motors are usually powered directly from coach batteries through a 100 amp re-settable breaker not the coach disconnect latching relay; the steps run off the chassis battery not coach battery typically. Sounds like your coach disconnect latching relay has failed open or there is an issue on the control wiring for that relay. I would monitor the voltage on your coach batteries until things are repaired, since you “may not be charging from alternator” on this chassis, by design. Maybe they changed things so I stand to learn something, as I always do. Good luck
