It showed 100% on the indicator but the battery was dead. I'm guessing that I was seeing the chassis battery?
Apparently, it's best to turn the use switch on before connecting to shore power to ensure that it's in the correct position.
I added this small panel to monitor the house batteries. It's connected right to the house wire at the relay. It also gives us a USB charging port at the table.

The battery level indicator indicates the voltage on the DC buss, not the battery itself. So if the converter is supplying power to the DC buss it will always indicate 100%.
