Well I guess i will have to put all your little "BOXES" to shame! Mine is still made right in Portland, Oregon.
Now I can tell you your backside will hurt some when paying for this beauty unless you are lucky enough to find one on CL for $300 like I did a few years ago.
It's a HighwayProducts, it's 30" front to back it has storage along the front side for oil and the such and a sliding tray that is about 3" thick at the top with several compartments. The new price is at least $1,000. If I were in the market I would spend that no problem.
This one is an application for a second gen RAM and probably others also. My point is if you like the tight fit get this application otherwise you will have about a 4" gap on each side so you can access the "D" hooks.
Oh, for the B&W haters just pretend the hitch is not in the pic. :B
