1st gen, Double Cab, Bed Organizer

Interested in seeing what folks are using as a bed organizer, in their first generation, double cabs. I already have the ratcheting cargo bar, but looking for something that will separate the read of the bed from the front of the bed, to hold gear in place. I recently installed a camper shell (yes!!!!) and as a result, can't use my tip out/tip in bed extender.

I do have the OEM bed liner and know that I can throw a 2x6 or 2 by whatever in the vertical slots on the sides of the bed. Wood is cheap, but heavy. Would like something with aluminum construction, light weight but capable of addressing shift of the cargo. Go!
