I settled on a "
Decked" brand storage system. Tis offers 6' long drawers
and a deck to fill the truck bed just above the top of the wheel wells. It is a "plastic - fantastic." By tat I mean I am not a large fan of most things plastic.
This is a molded lexan or poly something. It's tough & durable (supposedly).
Anyway I also found another brand nice to know about ( if your the patient type). Their name is Ainley. They make an excellent storage system that is about half price of a gun vault / truck vault price point. Below are links to both.
Ainley is a steel product. I would have went that route except for a July or August delivery date.
