I started building the drawers for my 100 yesterday. So far, I have built the outer part, added the center section and added the turnbuckles and their mounts to hold it down. I have the top done too, but it's not showing in the pics as I removed it to add the u-bolts. I added u-bolts to all four corners and hooked turnbuckles to them. I have spaced them so they can hook onto each of the four tie-down rings in the rear cargo area. This way, the drawer system is easily removable but loosening the four turnbuckles. I bought some 100 lb slides for the drawers. They are thicker than the nuts that hold down the u-bolts as shown in picture 3. This way, the drawer will not contact any of the u-bolt nuts sticking out. Next step is build the drawers and get them mounted to the slides. Then I'm going to cover the outer box with matching carpet and build a nice wooden face for the drawer fronts. I'll add pics as I get more done this week.
