First let me thank everyone for all their help.  I need just a little more reassurance.  I'm including some pictures as it seems that different pods have different configurations.
First picture is my panel box.
Next is behind the panel box. 

First are my labels correct?  It seems the AC ground bus is inside the panel box along with the AC common bus.   The DC negative appears to be behind the box.  Checks out with volt meter as I get 12v between DC fuse positive connector and both DC negative bus and AC ground bus.

So my inverter has a positive a negative and a ground.  I'm thinking this... positive to DC panel fuse (20 amp)  Negative to DC bus behind the box.  Now I'm unclear on grounding DC circuits and the difference between a DC ground an DC negative.  But I was going to take a ground wire from the Inverter ground post to the AC ground bus.  Does this all seem correct.
Thanks so much.  I'm going to get this... eventually.

Everything looks perfect to me.

Ground is ground irrespective of whether it's used in an AC or DC appliance.  So yes, you can use the AC ground bus for the grounding of your inverter, though most people do not ground their inverters at all, and they work perfectly fine.  It's just something that makes it a tiny bit safer.

For sure l turn off the ac power prior to wiring in the box. Do you normally unhook the battery or just remove the fuse for the circuit you are working on. Would be nice to install a battery on/ off switch.

Just to be sure, I would disconnect the battery, even though there's no possibility of the AC circuits being energized from it.

The battery switch is a very common mod, and it is cheap and easy to do.

At least in my 2016 179, you'll find that the bus bar mounted to the floor behind the inverter for the white wires actually also runs a line down through the floor and to the frame.

Unfortunately FR uses white wire for the 12V DC negative connections as well as the 120V AC neutral. White is the common color for household 120V neutral, but the 12V negatives should have been black. The 12V DC negative bus is the one grounded to the frame and may also have many bare copper wires. The 120V neutral bus will also have many white wires, but no bare copper wires. DO NOT CONNECT 12V DC CIRCUITS TO THIS BUS. Only connect 12V negative wires to the frame grounded bus. Use black and red wiring for 12V circuits to avoid confusion.
