Raised bed is a good idea because then I could sink the toolbox down and have it only stick up a couple inches. Plus the benefit of no fenders. I like it.
This is the storage bin i put under my flatbed.
It holds 2 drive lines, 2 spare CV's, hubs, tie rods, steering relay rod, idler arm, gear oil, scrap steel, misc specialty tools, etc.
I was planning on using trailer deck boards which would sit down in the angle iron and sit flush with the top of it.
I kind of figured that is what you were thinking, but I wasn't sure. Just don't go over board w/the thickness of the angle iron, anything over 1/8" is going to get be more than you need if you are looking to keep it on the light side.
