minor update, got the 0.3m cable for the bmv712 battery monitor. Seeing how it has bluetooth, I don't need to read the monitor much, just need to be able to reach it to stop the beeping.

almost done with the victron stuff. the solar mppt charger controller is working now, and the dc/dc charge controller is working. the dc/dc has to be wired to the ignition, but I was able to use a relay spot off the BANTAM spod controller that's mounted right near the boxes in the the truck bed on the driver side.
I'll do a final video when it's all done. Here are the slideshow updates, click here

Install day!
First got the back wall in the truck. A tricky manuever. And there's enough clearance I can still check and tighten the bolts for the camper struts behind the wall. Overcutting the window opening will actually help with that, so I'll just pretend I meant to cut the opening that tall, lol. The 3 holes in the upper left are for running wiring outside in the future. 1 will be used right away for the solar panel I'm adding.
Next I got the boxes close to in place, notice the pipes are not between the boxes yet.
And last but not least, the pipes are now in place with the wiring routed between the boxes. I then had to connect the 6 awg lines from the inverter on the right (the big blue box) to the ac/dc distribution panel in the middle left of the box on the left. I pretty much was laying on my stomach most of the time in the 90 degree heat, but at least I was in the shade.
Tomorrow I have 4 things left to do
1--make another video explaining the stuff above.
2--add the battery box on the right hand side in front of the big blue inverter.
3--drill a 2.5" hole in the drive side GFC panel for the shore power receptacle
4--add the solar panel and wire it in.
The first 3 tasks should only take an hour or so. The solar panel will take awhile because I have to building a supporting frame out of 80/20 aluminum, but I did a test fit, and I LOVE how it looked. Here's hoping the 80/20 stuff works the way I hope/plan.

wiring is almost done and ready for install in the truck. Here's a video.

I did find one photo showing the details of the box construction more. the box is upside down in this photo which helps. The face frame is mortised together with 3/8" thick x 1.5" wide x 1" long tenons. 3/4" inch thick poplar I had lying around. Very strong. The side plywood pieces are just miter cut in the corners, glued and nailed, so what gives the box the strength are the pocket screws connecting the plywood sides to the face frame. The pocket holes are then covered with wood plugs (you can just use dowels too). I trim the wood plugs over the pocket holes with my oscillating saw and then sand flush. You have to cut high, or you'll marr the bejeezus out of the plywood. Any oopsies get covered with wood filler.
Finally, you can see the back of the face frame with the T-nut hammered in place. This was done before adding the plywood sides via the pocket holes. Because the 5/16" star knobs are on the other side, it pulls the t-nut into the wood more when tightening the star knob down. They work great, very secure.
The rabbet cut in the back will first receive a 1/2" thick piece of Azek white board. and then there's still enough room for 3/4" thick plywood scrap to act as a mounting block/receivers. I may even french cleat the 3/4" plywood blocks. I'll paint the Azek before putting in the boxes. Just easier that way. I'll screw the azek in place from the back into the rabbets. the lip is a 1/2" deep so should be doable.
and yes one of those mitered joints is awful below.... but no one will see the inside, so idc.

Let the electric madness begin! I'm following plans and videos from Explorist Life, click here Very thankful they've put up such good content. Just spend $10 for the plans if you're going to try and do this yourself.. It's worth it.
Also, I got my Victron stuff from Battle Born. Contact them. Tell them what you're doing, and order through them too. They'll pre-configure your system for you. I also went over the plans with them, and they gave me a few tips that will probably save me some headaches (time will tell), but they're the experts, so trust them. Things will vary depending on how many batteries you're using.
This slide show explains more on what I've been doing, click here
The face frames of these boxes are mortise and tenoned together. the sides have pocket holes that screw into the face frames, which makes the boxes quite strong. The corners of the plywood sides are just miter cut, glued and nailed. The bottom of the boxes are dadoed/rabbeted so there's enough room for a 1/2" thick Azek panel to mount the stuff to, and behind the 1/2"thick panel room for 3/4" thick mounting blocks.
There's no way to install all this stuff on the wall piece in the basement and then carry it into the GFC camper. The grey coin laminate wall board piece on the bottom has to go into the camper separately. It has go in kind of horizontal to get over the wheel wells in the truck bed, and then you angle it up to make it the back wall. After that I'll carry in these boxes and mount them to grey coin wall. There will be mounting blocks already in place on the wall to make things easier.
Last note, I should have taken more photos of the box making process. but before the plywood sides were screwed to the face frames, I drill 3/8" holes through the face frames and then hammered in t-nuts on the back side of the face frame. I'm going to get some plexiglass to cover these boxes and I'll use 5/16" star knobs that thread into the t-nuts to hold the plexiglass in place. I'll add some tint film to the plexiglass so it's not easy to see what's in the boxes. I just need to be able to see through the plexigass enough to see the led lights on them, which tell me if things are running ok. The boxes have numerous holes for 3" diameter soffit vent covers, so the electric components can breathe and bleed off the heat. the boxes are deep enough too, so I can mount things on 1/2" thick wood strips so the heat fins on the back won't directly touch the white Azek back panels. A lot of thought went into this.
Anyway, next comes painting. I also need to make a battery box, so I can paint that too.
the t-nut and star knobs I was talking about above.
