My 3rd one!
It is a great product! I have worn and abused 2 of them thoroughly! I will ALWAYS use these storage boxes! They take a beating and keep on working until I just finally ruin one and so easy to replace!

More storage than appears!!
The UnderCover Swing Case Storage System for the Passenger Side of my 2020 Tundra is great. It was very easy and quick to install. The product was light weight, yet appears durable. It fits under the lip of the bed, snug on the wheel well, not taking any bed space. We were so pleased with the one we installed on the drivers side that we added the passenger. We were also pleased that it held more than we expected. Works very smoothly, even with a rhino liner installed first.

2023 Rubicon - DucksGuts
Really nice cover
Wanted a folding, locking cover with a scratch resistant finish that still gave full bed access. Although pricey, this was the ticket. Does it job well. Opens and closes, latches, looks awesome. The textured finish looks good and wont show any nicks or scratches and easy to fix. It did leak where the rails meet the plastic bed caps, but some black silicone eliminated that. Also nice is 2 screw wheels and the whole thing is out in 5 min. Not that you need to cause it open all the way with the props. Side note, i was able to make it work flawless with the Fishbone Chase Rack.

2024 TRD Off-Road - Joejoedarte
Perfect fit and easy to install
I have a 2024 Tacoma TRD OR 6’ bed. I did a lot of research looking at different designs and brands. The UnderCover Armor Flex stood out as the perfect fit for what I wanted. Extreme Terrain helped me get the order placed at a good price and it arrived in 3 days!! The install was easy and it looks amazing! The only thing I would suggest is during the install on step 5, line up the side rails to the adapter rail at the tailgate end (do not push the rail all the way toward the cab). You will get a much better fit and it lines up a lot better. I absolutely love the way it looks!

Great Storage Box
Easiest item to install. Four bolts and you're done. Holds quite a bit of stuff. Perfect for your hitch and various tools with quick access.

Great Concept, Well Executed
The cases are a great alternative to traditional toolboxes. In general, they work as intended, but the constraints of the truck bed make them less than ideal. They are just too small for some of the things I need to carry. The irregular design prohibits the optimum use of space. Having said that, they are a great match with a bed cover.
