SUT Tool Box

[kodiakz]

Any suters out there ever remove the plastic under the rear cargo mat? There is about 3.5 inches of space and I was thinking about making some sort of metal tool box to go under the mat. I was thinking about using diamond plate and then having the whole thing Rhinolined. I would hinge the front 8-12" with a handle to open a widthwise (is that a word?) door for quick access to tools, supplies etc. I was also thinking about sealing up the entire front half of the box for an amp or two and some narrow gelcell batteries (I think we have a small optima battery that will lie on its side in there). Any thoughts?
