Not the greatest shots, when I'm fully loaded up I haven't really thought to take pictures of how it's all organized.

This is kind of how it's organized, except I have two of the long cases that I can attach. They're weather resistant, not weather proof by any means, but they're inexpensive, large, and allow for loads of storage without being a total PITA.
In the first two, we were fully loaded for about a week of camping and biking, each person had one of the large cases for personal gear, sleeping bag, helmet, etc., one of the smaller ones is dedicated to recovery gear, compressor, straps, etc., and the other was cooking stuff (we had way more crap than we needed). In addition I have a 15lb CO2 tank on the deck, and two Rotopax gas and water cans below the deck behind the cab (see Mark fiddling with that above).
My issues with this system are that, when fully loaded and with bikes, access to the cargo in the middle is difficult at best. These boxes are NOT very rigid, and I want to switch to another variety, they are fine if you don't overstuff them (they bow out), they're better if you don't attach them with turnbuckles as I do, if you strap them down they're fantastic. I'm debating tweaking the method in which I attach bikes, possibly raising the rear wheel and using a pair of larger boxes that would span the width of the bed toward the back. Alternatively, I'm thinking about building a bed slideout that would bolt to the deck, allowing me to pull whatever is stored between the bikes out to the back.
In addition to what's on the bed, I had my camera bag, our hydration bags, and cooler in the cab. Not ideal, but it is what it is.
