Far superior to stock

Rigid enough walls, far superior to stock storage in 26' GMC 2500hd AT4X. Much more useable storage under the rear bench seat. Only negative for me is the product name on the side, large and more visible than I'd like. I'd rather it blend better, but product endorsement is more important to the manufacturer . I'd pay $5 extra to have the name moved to the front, or somewhere unseen when you open the doors. Thanks

DU-HA Under Seat Srorage Bin

This under-seat storage bin is much better than the ORG stock unit that came with the truck. It is a bit deeper and a fair amount taller. It's almost as high as the rear seat when folded down. The location of the removable compartment dividers are well placed inside the box and much improved from the ORG stock dividers. This was a good purchase. I wish the storage try they came in more colors to match the interior.

Under seat storage

I received my under storage in a timely manner. The install was quick and easy. It fits perfectly under the rear seat. My only issue is, I wish it had a top /lid so that I could close it and conceal whatever I am putting in it. Other than that, a great product. Thank you.
