Here's one I built for my last truck. It's not exactly what the OP is looking for, but may give some ideas:

 

Very nice that is some quality work. I love the tie downs and the gussets. Nice job

 

Got my vintage tool box installed

 

Yeah so I didn't really want a silver tool box but it was cheep and it is a tank. I have learned from this experience that I never want a steel tool box....I'm telling you I can get this aluminium in and out by myself but it's still a handful. There is no way in hell I'd be able to handle a steel one. Mine is just the "normal" size and it is huge on the inside. I'm a believer in the strength (and weight) of aluminium.
