Under Seat Storage Box
Pros: It keeps all those extra loose tools and straps from rolling around in the back seat. It comes with dividers to separate tools and straps. Cons: The under seat storage box slides around, the clip always becomes undone. The dividers are flimsy hard foam pieces that don't stay in place.

It fit!
I only say it fit because I have had bad luck lately buying items for my truck. It fits great, works great....only thing I would suggest, is another point to secure it with/from. Other than that, Awesome!

Neat Backseat
Product is very helpful in keeping backseat clean. No longer are there items rolling around back there. I can keep an umbrella, gloves, jumper cables, fire extinguisher etc all under the seat without anything rolling around. I thought about making one myself but the fit with this item is so much better it was worth buying!

Good value, sloppy fit
Little disappointed with the way this fit, while it sits in place ok and the seats close just fine it is just a little sloppy with the seat bottoms up. Its fine and I didn’t think about it till asked to review the item but the reality is this feels like something molded to fit a large variety of trucks not just mine.

A perfect fit!
This storage fit perfectly in my 2018 2500 High Country when placed on top of the WeatherTech floor mats. The strap was easy and quick to install and there is no movement when driving. Definitely worth the buy if you have been wanting to get one.

Installed with little effort. I like the idea of the items not sliding all over the place.
