I've got a 2012 F150 Super Cab and am looking to install underseat rear storage. Does anyone have a DUHA box that would like to offer an opinion?

I have one on a Chevy and it's the best thing since canned beer. I can fit two rifles, a fire extinguisher, first aid kit, ropes and straps, oil, paper towels and hand wipes, a 10-22 takedown, handguns, ammo, etc. etc. etc. They ought to roll off the factory floor with one installed.

Not much to complain about with the DUHA except maybe the price.

Yeah, the price is a little high considering that all you're buying is a plastic box. Nonetheless, I ordered one in black.

It wouldn't take a whole lot of work to make one from 1/4" plywood.

You're right, but I'd have to find the time. It's because of guys like me that companies selling plastic parts at inflated prices stay in business.
