I'm thinking in the rv there are lots of connections to ground. Most everything is landing to the chassis in one way or the other.
Mine has a ground bus bar under the bed, in the area behind the converter where the birds nest of wires are.
The house battery has a connection to the chassis
the chassis battery also
and there's several wires grounded to the fender near the battery isolation relay (BIRD system) under the hood on the fender.
and on and on....

what problem are you chasing?

Then you need to check the ground connection for that panel.

I'm not familiar with your particular coach but most standard monitor/switch panels are simply flat panels screwed to a hole in the wall where the wires disappear into. You can remove your panel, locate the common ground wire, and then chase it to where it attaches to the frame/ground. You may find something as simple as a loose wirenut connection.
