Rather than try the one size fits all box, I went to Walmart and got a series of interlocking plastic drawers (with holders) that I piut in one of the smaller compartments. 3 wide 5 high. Put a number of sockets, screwdrivers, pliers, fuses, meters, hammers, etc, in each with labels on the outside. Also, in a compartment with a large slide tray I put a piece of plywood between floor supports where I store plastic fishing lure boxes with screws, washers, nuts, cotter pins, o-rings, and all the kit boxes such as heat gun, manometer, small socket set, Dremel and pieces, electrical butt connectors, splices, and terminals, etc. Since this storage area is above the bottom of the frame rails, it was wasted space. I'm an old farmer and mechanic and feel naked without ALL my stuff. Has worked very well when I have a problem on the road in a remote area of Yukon, BC, Alberta, Alaska, and even the southwest. Only down side is the extra weight, but I'll gladly pay that freight. Sorry about no pic's, but I can't seem to get things to post right. If anyone's interested, PM me with your email address and I'll send .JPG.s back.
