Low Profile Job-Site Box Options

[Alex Hardy]

So here's the deal, I recently got a magnum rack with a low profile tonneau cover. I have always had a crossover box in the past.  My current issue is I need to have a tonneau but would also like to have a box in the bed I can slide my shovels and bars under, yet still have something heavy duty for my chains and other tools.  I do heavy civil earthwork and this truck is my rolling tool box.  I know carpenters and usually building trades usually use Knaack, Jobox, and other brand site job boxes.  I've done a little bit of research and am leaning towards a Knaack 18.5" tall box because you can fit things under and also i could use a loader with forks to removed it from the bed.

 

Does anyone here have any experience with lower height (<20", to fit under tonneau) jobsite boxes or tool boxes.  Any input or advice would be welcomed.  I will post a photo of the set-up when I get a chance later.
