The shore power cord's bare copper ground wire should go to the power centre's metal case and then to the rig's frame. Its neutral goes to the neutral bus and the hot goes to the main breaker.
The converter is a 120v appliance with a three prong plug and that ground prong touches the receptacle wire's own bare copper that goes back to the power centre's metal case (which is grounded to the frame)
The converter has its own metal case (chassis) with an external ground lug that should be wired to the frame separately (ie not via the converter's 12v neg output) with a wire (gauge is in the installation manual for the converter) if it is a deck mount converter away from the power centre.
If the converter is with the power centre, the converter's metal chassis is touching the (already grounded) power centre's metal case, so you don't need to wire up the converter's chassis ground.
The battery and 12v systems are also negative grounded to the rig's frame, so 120v and 12v both share that ground.
