Crazy bed toolbox idea?

[luke1968c10]

I was watching an episode of The Fall Guy on Hulu a while back and he opened a big door on the side of his truck bed and it was a big box that went across the entire bed under the roll bars. I have to re-do Ol'Green's bed again(Never use bondo in the bed of a truck that hauls big loads on a regular basis.)And I got new bed panels front and back that would have to be welded together right above the wheel well.
I was thinking about making the front section open suicide door style and reveal a big tool box, but only in the bed side and possibly as deep as the wheel well on the inside of the bed. It would be a place to store my spare, jack, and lug wrench along with some other tools. Am I crazy or does anyone else think this would work?
