Hole? Could you explain what you mean?
I've modified my trunk area, as many have, but use an entirely different approach. Well, maybe not entirely, but I increased the trunk space by about 3 cubic feet. The chassis is at the powder coater and I didn't take pictures yet.
With regard to "....one complete sheet of aluminum", the top of my deck is is even with the bottom of the side 2x3 tubing. In addition, I have the typical open storage area beneath the deck. The hinged cover over it is also removable.
