A more useful tool box
I've had a molded plastic Contico SUV toolbox since my first truck, a '97 Ranger with step sides that made nearly all toolboxes too big. It doesn't carry much, and it's a weird shape.
With my Frontier, I have a more useful bed, and with the Utilitrack, a lot of flexibility in how I mount it. There didn't seem to be much consensus from y'all on what a good trail toolbox looks like, other than something that would be too big for my daily driver. Certainly nothing that would fit with the fiberglass tonneau cover that came with my truck.
The reviews for this toolbox
were underwhelming, but the price was right for something I knew wouldn't get too abused. It arrived a day earlier than I expected, leading to battles with my son to stay out of it. The reviews were pretty accurate: thin gauge steel, holes in the bottom, uneven paint. At least mine arrived undented.
I had all the other hardware that I wanted, namely spring nuts and eye bolts.
Scrap 2x4 would serve as the mounting base for the box. I could explain this all, but I'm sure that you'll figure it out from the pics.
Before mounting the box, I test fit the 2x4s. Turning the spring nuts will require a screwdriver, but they also do a great job securing the box to the Utilitrack rails.
To mount, I silicone caulked some rubber washers inside the box around the existing holes and attached it with some stainless screws.
It doesn't slide past the screws in the track, but it's easy enough to lift it out of the track if I need to move it around. Shrug. The eye bolts will double as cleats when I need to tote lumber home from the hardware store.
There it is. A toolbox not made by Nissan for our truck that costs way less than theirs.
