Nice day to hide in the storage compartments and run cable. Don’t have the MultiPlusses connected to the battery bus yet, but wired another solar controller in and also ran some of the CAT5 cabling in some loom. Getting there.

Nice clean connections and looming but I think you forgot to cut a zip tie so I’m giving you a -1 rating for neatness! Looks darn good to me but I don’t care about much the older I get.
Just wait till your my age, you can surprise even yourself with some of your opinions. 
Working on the splitter/combiner boxes. The 120v in from shore power needs to be split to go to each MultiPlus, and then the output of each MultiPlus needs to be combined so that it feeds the rig’s 120v system. And to keep everything in phase electrically, the 120v wires need to be the same length. 6/4 wire is pretty stiff to work with, but I’m using finely stranded wire so its a bit easier. And I am using color-coded, rail mounted connectors inside the box for ease of assembly.
If you have the time I’d love to see a block diagram of all your components and the basic connections.

This is a rough diagram of where I’m going to end up.
The 120v goes from shore power, through the Power Watchdog, and splits into each MultiPlus. 120v leaves each MultiPlus, combines, and goes to the 120v panel.
The 12v side consists of 800ah of battery, connected to a Lynx bus bar, through the shunt, to another Lynx bus bar. All loads are off the second bus bar, so that all battery power goes through the shunt so it can be measured.
Everything connects one way or the other via comm lines to the Cerbo GX, and the monitor screen.
This project has allowed me the opportunity to buy a bunch of tools. Among them is a ferrule crimper.

I have the same brand, but the 6-sided version. Fun tool, isn’t it?
Any excuse to buy a new tool or twelve is a good one.

Getting down to the wire (wire, get it? HAH!)
Anyway, getting the 120 side of things started. Have both MultiPluses wired to the splitter/combiner boxes. Wrestling with 6 gauge wire is ‘fun’.
Both multiplus wired in.
The AC in splitter box. 120 from shore power will come in the left side, and splits to each MP. The combiner box will do the same thing, only backwards (From the MP to the circuit panel in the rig)
Closeup of the MP wiring. Left to right is AC out, AC in. Chassis ground, then the CAT5 wiring for communications to the rest of the system, and then the 4/0 battery connections.

You missed two posts 
Are those for a second battery hookup
Buttoned up the front compartment today. Both MultiPlus wired to their splitter/combiner boxes, and the 120v wiring run up through the passthrough. This weekend I’ll get all that connected, and then give it all a test run. Once I’m happy I’ll be adding more wiring loom and ties.

I have replaced the flip-down whatzit sponge holder thingy in the kitchen with a more useful (for us) drawer. Maybe a couple hours of work overall, including routing out the back of the drawer front, since the drawer that I purchased is slightly deeper than the space available.
We’re just back from 27 days camping in Maine. Sebago Lake, Belfast (Right on the water), just outside Acadia National Park, and Boothbay Harbor. Batteries and all worked fantastic. Would lose less that 2% capacity on travel days (typically a 2-3 hour drive) and only lost 4% on a 6 hour stretch when the campground lost electricity.
I had almost no connectivity of any kind on the road, and I can’t say I missed it. Being unplugged was pretty freeing. Last night we had to pay for camp WiFi because Martha had a board meeting on Zoom she had to attend.
Yea, having Penobscot Bay right outside your camper 100 feet away isn’t too bad.

I grew up camping off a finger lake of Sebago , listening to the loons
So is that your get naked and swing into the bay steam powered wrecking ball swing or do I sense a Victorian touch with a burl walnut roller shade pull.
If you cropped out the shade then no one would know you have a taste for Victorian era shade pulls and you could sell them on the naked wrecking ball swing thought.
Party on man!
