there has been some interest in my storage setup in my YJ, so here's a quick write up. all pics are at the end, I'll try to get them in order.
I had given thought to getting one of those pre-made trunk deals, but just couldn’t justify the cost, and didn’t want something that was permanently mounted to the jeep. after many hours of thinking, measuring, sketching, re-thinking, and re-drawing, I came up with what I think is a pretty good solution.
I came up with a modular storage system that lets me retain the use of the rear seat, but also gives me the option of enclosing the entire rear of the jeep with a hard tonneau cover.
I started out by building two boxes that are mounted to the top of the wheel wells. The boxes follow the shape of the wheel wells, and the tops are flush with the top edge of the jeep body. The boxes are a little small, but they have plenty of room for my tow strap, jumper cables, clevises, small compressor, tire repair kit, and a few other miscellaneous items. I also added padding to the lids of the side boxes, which make great arm rests when the rear seat is in.
With the side boxes complete, I moved on to the trunk/bulkhead portion of the system. It’s pretty much like any other “jeep trunk”, it fits behind the rear seat, and seals against the tailgate.
Now, here is where it gets fun. I attached the trunk with quick release attachment points(I’ll describe how I made those later). With the rear seat removed, I can move the trunk forward to just behind the front seats. In the forward position, the trunk serves as a bulkhead, and as an attachment point for the tonneau cover.
To attach the tonneau cover to the trunk/bulkhead, I modified an old set of hood hinges that I had. I cut part of the hinge off, so that they slide apart just like the factory door hinges.
I also made some brackets for some gas charged struts to hold the tonneau open. One is bolted to the floor with the center seat belt bolt, and the other is on the under side of the tonneau cover.
Ok, for the quick release attachment points, I took some stainless steel cabinet door hinges, and punched out the pin. I replaced the pin with a 1/8” “hair pin” style cotter pin. Then I attached one side of the hinge to the floor, and the other side to the trunk section. To remove the trunk, all I have to do is remove the cotter pins, and the hinges can pull apart, and the trunk lifts out.
