I've got that 'box' and I wouldn't recommend it for a TJ. It is quite bulky and you have to split it in half to open it. So any weight in the top half of the box you will have to lift off while fiddling with the latches around the sides and back. It is certainly a good quality box, but isn't well suited to carry parts or tools or be located in a small restrictive space. It's good for holding your summer clothes for winter, or winter clothes for summer (if you have a lot of summer clothes) and slide it into the closet. Then have 2 to open and flip the upper half while keeping everything from falling out on the ground.
