1. It blocks the light for the bed.
2. Because of how the bed is made it does not sit on top of the wheel well and you do loose a few inches of bed space. If you add both sides you loose a lot of bed sapce.Look at pictures.
3. You can take it out of the bed and take it with you BUT... no handle to carry. This product claims to hold up to 75 lbs. I cannot imagine being able to load this with 75 lbs and not having some sort of handle to carry it out and since it has an odd shape it would be hard to carry.
4. Locks are cheap. Not the quality expected on a $200+ box.
5. Cup holders and tray are very shallow. You put any drink there and with any minimal movement it will fall.
6. I'd you have a bed cover that you have to hook to the edge of the bed for it to close the box sits too high for the handle to clip onto the bed.
Pros:
1. Extremely easy install. 5-10 minutes max.
2. Holds quite a bit of gear
3. The swing out feature is great.
UPDATE -
After using this item for a few days I can confidently say that it is NOT WORTH IT!
If you have a bed cover on your truck DO NOT BUY THIS! You would need to open the cover everytime you want to open the case. The cover get in the way when opening this item. It's just not worth the hazzle or the prize for something not too functional.
Top reviews from other countries



Going to break this review up into to two parts A) General Comments and B) Installation Advice
General Comments:
- excellent for the price point.
- GM side mounted boxes are over $1000 and not easily accessible.
- Swing Case box and contents easily accessible while tonneau cover is still closed due to the convenient latch location and swivel function.
- few reviews about how they could have made it tighter to the bed wall but I like the fact that I still have access to my tie down loops while it’s closed.
- it does project out past the wheel well by a few inches which may interfere with transporting 4x8 sheets of material flat. However the box can be removed in seconds and very easily which is super convenient.
- yes it does block the 12v plug but the plug is still accessible if needed.
Installation Advice:
- you need a cordless drill, 9/64 drill bit, 7/16 socket bit, and a Sharpie
- instructions are pretty straightforward
- I am one for measure twice cut once so I may have taken a few extra steps but zero issues with fit, alignment, or function. Instructions provided by manufacturer are pretty straightforward however.
1) I used the hole plug provided to temporarily mount the hinge and mounted the box to it.
2) I used a few items (see pictures) to shim the box in place until happy with my bracket alignment and the the way the box sits and clears. Manufacturer Instructions show placement points and they are pretty spot on.
3) once happy with the bracket alignment pre-drill your bottom hole on the bracket then secure with the screw included using the socket bit. One screw and the hole plug are enough to hold the weight of the box while you adjust your striker bracket for placement. Again placement on manufacturer instructions pretty spot on.
4) reach under the box while mounted to hold your striker bracket and use a sharpie to verify location. Once satisfied, install the top right screw on the striker bracket. This will a) hold it securely in place to check alignment and function as well as b) allow you to twist/move the striker bracket if needed to ensure smooth latch function. DO NOT INSTALL ALL 3 SREWS AT ONCE or you won’t have an opportunity to adjust the alignment.
5) once satisfied with the latch function, secure another screw into the main hinge for firm placement. Remember to pre-drill the screw holes rather than just trying to drive the self taping screw in. By just driving the screw in without pre-drilling you risk moving the placement of the hinge.
6) verify the box and latch function again and once satisfied secure the striker bracket with the remaining 2 screws
7) install the remaining 2 screws into the main hinge.
8) install the pivot lock
9) Enjoy!!!
I’m just providing a few more steps that I took during the install to ensure proper function and alignment the first try. The manufacturer instructions are good and if you’re handy you should have no issues at all.
Will update review if I’m noticing any functionality issues.
Enjoy!

Only issue I've had is when running a 5th wheel hitch. When I roll it to the rearward position, or when I remove the entire hitch, it impacts the toolbox. I found this out the hardware and mangled up the adjustment lever on the hitch. Amazingly I was rolling the hitch back (with full trailer weight) and the hitch bent but the tool box was unscathed. So it is really strong. I believe I can cut down that adjustment lever and have all the functions.
It's my intent to eventually pick up the passenger side as well.
