This is version 3 of an SUV Cargo Storage deck that I’m calling a Drawerless Drawer System, and I think I’m done for now.

Here's the build video with full process. At the end I address the critical measurements. Keep reading below for more build details and measurements for a 3rd gen 4runner.

The first version was a deck platform above the cooler. That worked fairly well when loaded, but for daily driving having the deck that high wasn’t convenient.



Second version I made as my first welding project. It was ugly, but the low deck and slide-out table made it a much better design.



Single Sheet of Ply Wood
This build can be done with a single sheet of plywood with two squares and one shelf board left over that will be suitable for other projects.

Home Depot Panel Saw
Start by having someone at Home Depot cut down your 4 x 8 sheet of 3/4 plywood on the panel saw. The measurements aren’t super critical, and the panel saw is good enough. This is a cargo deck after all, not heirloom furniture. The measurements I used were for a 36″ x 48″ top with 12 inch sides. Your measurements might need to be different, adjust accordingly.
* 2 pieces @ 36″ x 48″
* 2 pieces @ 12″ x 48″

Chop Saw
I cut down the sides to 36 inches with my chop saw. I had to flip them over as the saw wasn’t able to do 12 inch in one pass. Using a stop block makes this a lot easier.
* 2 pieces @ 12″ x 36″

Skill Saw
The only other cut is to cut down the slide-out table to fit inside the uprights. The measurement I used was 37.5 to fit within the wheel wells which are 39″ apart. I measured the off -et on the frame of my circular saw and set up a straight edge to act as a fence to make this cut straight. It wasn’t perfect, but again, this is a cargo deck for a 19 year old 4Runner…
* 1 piece @ 36″ x 37.5″

Finishing
I recommend using a water proofing finish on this. I will spill water on it, the cooler will leak. The dog may be wet when she gets in.
For the slide out table I didn’t want to use water seal, so I got some bees-wax butcher block conditioner that is food safe and applied that. I will re-apply that periodically to keep it protected. I put it on the sides and the finger holes to help keep it from swelling itself shut if it does get wet. I left the underside of the table and the deck unfinished to aid in drying if it ever does get saturated.

That looks really cool. I'm currently working on a wood floor with fold up walls, my needs are usually more utilitarian(scrap metal, 2x4's).

Very nice!
For my 5th gen I made a cargo platform with a similar design for the pull-out drawer. I originally made it as just a 2.5 inch leveling platform in order to sleep in the back. It worked well but I wanted additional gear storage while camping with my wife, so I made version 2.

I attached 3/4 inch pipes with flanges to raise it up about 10 inches. I then made another platform for the front section which is also raised on pipes and flanges to create an almost 6.5 feet long sleeping platform with storage room underneath. The two platforms are snugged together and to the floor with turnbuckles. No rattling and I remove the front platform section for daily driving. The photo below is just the rear section.

By the way, I enjoy your other YouTube videos.
