I was inspired by some of the other custom boxes that other people have built on here. I hated the slide out cargo tray, so I decided to dig up my old woodworking skills from shop class back in High School (rusty at best). It still has some finishing touches that I need to do (cut off screws) but for the most part I think it came out ok and will serve the purpose that I built it for. I wanted something that could be removed yet not take up all of the room in the back from the dogs and work well when the seats were down. In it I have created a "wardrobe box" for spare clothes, boots, and emergency/survival kits. In the larger box I have a toolbox, on board air, fire extinguisher, tow straps, and some other random things. The dogs seem to like it.
