I don't know how long your coach sat on "shore Power" before your chassis battery was dead, but the chassis battery will discharge below the voltage needed to start the engine. How long that takes depends on the battery, coach and battery drain. That being said, if the coach was on shore power, it should have kept the chassis battery charged. If the chassis battery is now charged after your drive home, I would plug it in at home and see if your shore power is actually charging both your house and chassis batteries. If not, there are a variety of different reasons why it may not be working. If it is, it may have been a problem with the shore power or something that you have already corrected and I agree with gmc, chase it if it happens again.
