This from an electrical dummy………
When I installed a 1000 watt inverter in my 5th wheel, the aluminum frame was handy to use as the inverter chassis ground, so I drilled it and used it.
On my slide in camper, there are no exposed frame members, and thinking that the battery is grounded to the frame anyway, it would make sense just to ground the inverter chassis to the negative terminal of the battery.
Make sense?

I think with any wiring it is always better to ground to the battery or a block that is properly grounded. Poor grounding is a common problem with wiring.

I would either skip it or pull a separate ground wire direct to the 120v load center and connect to the ground bus.

Point taken: OP Are you asking about the DC negative cable or a separate inverter AC chassis ground?

No. Do not link the inverter chassis ground to the inverter's neg input. Going to the battery neg does that. The chassis ground should go to the frame independent from the battery's frame ground.
As suggested, you could connect to the metal casing of the power centre that has the 120v breaker panel in it. The shore power cord's bare copper ground wire is grounded to the frame from there so that makes a path for the chassis ground to the frame
You can just not use the chassis ground at all, since it is for reducing radio and TV interference.
