Underseat Lockbox
The Tuffy Sercurity Underseat Lockbox is well built and fits perfect. The only problem is that I think it is overpriced.

Fits great
So the box is awesome. However when I got my package all the hardware was in the box. However so was the paper that said what the code was to unlock it. Lucky I just tried all zeros and it unlocked them. But that’s all I have to say bad and I’m not sure if that’s on this company or the manufacture of the box. Also I ordered foam from Amazon I have coming to line it with foam you’ll need it for sure. Also added led light strips to my box so I can see in it.

Lockable cab storage for Colorado
This is one of those products that just works well and solves the problem. There's no secure storage anywhere in the cab of the Colorado, until now! Relatively easy to install, fits perfectly, offers plenty of useful space, and is basically invisible to everyone. It's very well constructed and actually improves the looks of the second row by providing seamless support for the rear seat. The 60/40 split locking cover is very useful and matches the seat split for easy access. I had to purchase a T47 Torx head bit to get the factory seat support bracket out, but that's it. It's a little bit spendy but well worth it.
