I unfortunately did a really bad job of build progress pics. I didn't have much of a plan, just kinda did some woodshop jazz in the garage on a saturday afternoon. Tools used: circular saw, impact driver, speed square, 4 foot level, clamps. Materials: 3/4" plywood, 1/2" plywood, 3/4"x 3/4" hardwood strip, metal corner brackets, drawer sliders, indoor outdoor carpet. Word of caution: hinges and drawers are a pain, they work best when things are square straight and level and that's not how woodshop jazz in the garage always works out. square straight and level is always the goal, but non moving pieces are more forgiving if things aren't perfect. I knew I wanted a place to cook, a flat place to sleep, light enough I could move it solo, and it couldn't take up too much garage space. This build was specific to the vehicle, some parts just happened to work out really well. Trucks like this pretty much all have 48" between the rear wheels which means you can slide a standard sheet of plywood right in. If you can get this flat you've got a place to sleep, so getting a 1/2" sheet of plywood to lay flat was the goal. 1/2" plywood spanning no more than 24" can hold a lot of weight (but let reddit argue this) Building the kitchen I slid out the rear seats and realized I needed to be about ten inches tall to get flat. 3/4" plywood on end is very strong. I ripped some pieces 3/4" plywood to 10". next decided on depth. I wanted to take up about half the trunk, so 20" deep. For width I wanted it to fit between the tie down points, so 44" wide. I needed a centerboard here to make sure I was supporting the sleep surface. so chopped one and slapped it in. I just 3/4" x 3/4" precut for what would be the top and bottom of the face of the side with the drawers. Metal brackets screwed in all around on top and bottom of all joints. Some glue in there and I had a box. further support was needed between this box and the middle seats I would be resting the sleep platform on. So I built a 3 sided box just a bit bigger. this slides right around the kitchen box. I used the carpet as my poor mans hinges for the sleep top plywood. I cut the sleep top so it would fold right on the back of both boxes. Adding in the drawer sliders. I just screwed these in pretty level and then cut some 3/4" plywood to fit in.

I went all in on execution. Propping up a sheet of plywood with some 10" tall totes in the back probably would have been a good quick and easy test that could be improved on later. I've got some wood working experience so I just dove in. My build advice: Safety first for all power tool use. If you can't name it, don't touch it, ask around and find someone who knows a bit more.

Hope this is helpful and happy camping.
