You can see the inside of one of the cabinets here. There's a 1x3 that stretches all the way across the top of the van, bolted with rivnuts every 2ish feet. Then the cabinets are bolted into that. Have gas struts on all of them to hold the doors up.
Sink is 14"x16", and 8" deep (bar sink), and a normal kitchen faucet (I hate the van builds with shitty little faucets). The soap dispenser is actually the 2nd one. I really like it, but it was free hanging and on a trip to Yosemite last year I guess it was brittle and broke. Pictures under the sink later where I hope I've solved that. Using Dr. Bronner's soap we can dump the "grey" water anywhere (biodegradeable). There's also a cutout for the sink (in my last pictures it was in the sink) if we need the counter space. I doubt we will, cause that's a shit load of counter for a van.
Same deal as the bottom of the rear doors, except there wasn't a black plastic piece on the top there. It was just an open cavity. Installed some smaller rivnuts and put those in. I should also mention that I treated those pieces of wood, and a massive spot around the sliding door area with a mold/sealant product so that hopefully the wood doesn't have issues with water. I also on the last build had spackled and painted over the screws for the walls, but spackle doesn't hold up super awesome with 70-80mph roads. Oh, and I should also mention now about the framing. So I have 1x3's at the top there, but there are also ones running along the middle part of the van and bottom. There are then "floating" ones connecting all those, essentially like you'd have framing a wall (although the spacing is weird because of the van shape). So essentially if I took all the walls off, you'd see wall framing with insulation between it.
Anyway, there are also soft close hinges on all the cabinet doors, which you can see. As well as the magnets to hold them closed.
One of the things I dislike though is how the cabinets aren't completely flush (you can see the difference in this one between the old cabinets above the bed, and the new ones above the kitchen). Because of how fucking wonky the van, it was a god damn nightmare to get stuff flush. The cabinets below the sink used to be flush, but when we took them off to paint those got fucked up too. Oh well.
This one has the window. Came after the fan, but because it's not on the roof where no one would see (the van is like 8'6" I think?), it was so much worse cutting into the side. Dog fucking loves that window though. We take the reflectix cover off in the morning before we get up so she can watch.
Here's the electric, sitting behind the driver's seat. On the left is the fuse box (fan, main ceiling lights, rear ceiling lights, water pump, USB, fridge) and a fuse from the solar to the charge controller, middle is the charge controller which is hooked up to the battery, the solar panels, and the fuse box. Next to it is the battery isolator (connects to house battery and van battery; allowing the house battery to charge off the alternator). Below is a fuse between the battery and charge controller. Bottom is obviously the 100A lithium battery.
On the right side is the 1000W inverter. It has an extension cord that I just chopped up and connected to a normal 110 outlet. Previously I had a chain that also had one on the ceiling (we had a projector, but it was an asspain to set up so we decided to not use it anymore), and then one on the passenger side (which is now that light switch). We realized we don't really need 110 power that much though. The inverter has a GFCI built in. Below the inverter is another fuse between it and the battery, with a heavy duty switch to shut it off. Battery, isolator, and inverter are grounded to the one of the ribs of the van. There's also a false floor behind the driver's side (in that shoe thing I built) where there's a fuse between the isolator and van battery, and another one of those switches in case we don't want to charge. The isolator has a button you can push to reverse the flow in case you need to jump your car battery
Last one, under the sink for the plumbing. Flexible p trap so I can unhook it from the grey tank (Home Depot bucket) easily. Ideally I'd like to get a 5-10 gallon water tank and mount it under the van, and then just run the drain through the floor. Left side is the water pump (12v), and it runs to a water accumulator which helps even out the water pressure so it's like a normal sink. Only thing is we don't have hot water. You can see the little housing I built for the soap dispenser. The piece of wood right below it comes out so I can put the bottle back in (screws in). We also had an issue last year with the barbed connector between the accumulator and tubing springing a leak (I think it got heavy and just pulled down over time), so now I've got a bunch of velcro straps to hold it up and keep it straight. It got water fucking everywhere and I was super pissed for our whole trip. I probably should've done this in something like PEX, but for some reason I couldn't figure out how to connect it to the pump. Just weird sizes and shit. In fact, I spent HOURS in the Home Depot plumbing aisle coming up with solutions to even get this shit working. I had to solder this fucking bizarre ass 3 way valve in order to get the tubing to connect to the two water lines for the sink.
Anyway, that's about it. Think I covered just about everything, Chuk.
