Sorry Rezarf...I wasn't giving you a hard time at all about searching...I know you know how to do that. Here's the thread I put out there a couple of years ago.
Drawers with some plans
After seeing all of the other great builds out there there and using my drawers a lot...here are some things to consider. I love having the drawers at the same height as my 2nd row seats when folded down. I have slept inside my 100 series several times and that works out great. It also makes putting things like groceries and kids' sports bag in the rear and retrieving them very easy.
1. I am not a carpenter, so my construction is a little rough. With that said, I would have simply made a single unit, vs. two. Less wood. Less weight. Easier to build. I have never split them up, using only one side and not the other.
2. I think with some internal dividers, you can work with a single drawer vs. two. Just be careful not to overload it. I am sure there are pros and cons with one vs. two drawers. With one drawer, you have more useable space overall.
3. I would have made the length of the overall build just maybe 8" shorter with a hinged lid, toward the 2 nd row of seats, so you have a full width storage space between the back of the box and your seats. I would use this to store tools, recovery gear or possibly a shot gun or rifle for hunting.
4. I use the space between the sides of mind for all kinds of storage of stuff from my hatchet, ropes, a spare towel, jumper cables, first aid kit , my cb antennae when not mounted, and tons of misc. stuff.
5. I would have taken the time to mount the drawers to the 3rd row rear seat bolt holes.
6. A slick little trick I did, so my drawers will not slide shut when parked on a slope, is when fully extended, I drilled a hole in the upright side of the drawer, right next to the top of my drawers, so I can simply drop a nail with a larger head on it in there that I can pull up and let gravity do the rest. To close the drawer, I pull the drawer out 1/2", drop the nail back into the hole and close the drawer. Cheap and effective slide lock.
7. I used 3/4" marine grade plywood. That may have been overkill. But I really don't ever worry about moisture warping or tweaking my build. You can get by with 1/2" plywood, no problem.
