Wow! Totally awesome field box!
Here's mine. Complete with motorbike battery, paper towel dispenser, model airplane saddle/stand, tool pocket on side, fuel can section, two level main section, and of course AMA stickers.
This box is totally home made and designed by me. The cool part is that I am able to just keep adding different things to it. Originally it had no side pocket, no paper towel holder, no airplane saddle, and the fuel can was on the inside instead of the outside. It has its problems, and is not nearly as cool as yours, but mine gets the job done.
