Following the debacle wherein I did not have any recovery gear, I sought to remedy the situation. Previously, I'd used a rigged plastic trailer box, but it could not hold much weight, so the heavier items were left out, especially after the box started to break. I scrapped the plastic box entirely and bought a sliding tool box from the Nissan dealership built to sit on the Utili-Track rails. It anchors to the cab with a slide-lock and can be unlocked and slid all the way to the tailgate when performing work that requires it.Great utility. Moreover, the box is sturdy and rugged, has a nice low-profile, and a very deep compartment that I've still not managed to fill entirely in spite of the gear I tend to pack in there. I've not had any water get into it, either during intense rainfall or even running through a wash-rack and blasting it with a pressure washer.With the box in, the next project was light, but without the factory roof-rack, mounting options were limited. I decided to go with the STK Pro-Rack to give me a nice, firm option to mount lights both front and rearward facing, as well as for the looks (it's got a nice, clean style to it that I enjoyed).The only problem was that the STK Pro-Rack, once installed, would not allow the sliding box (which came first) to slide all the way back, much less open to access the locking mechanism.After shopping around, I found a spacer kit for the bed extender offered by Truxedo. The aluminum blocks were built to allow the bed extender to function while using the Truxedo tonneau cover and were relatively inexpensive. On a hunch, I bought a set.The installation took some creative thought into mounting the brackets, but once done, the fit worked out like a charm. The box has just enough space to snug up and minimize the gap between the box-lid and the Pro-Rack's base, but nothing interferes with anything else. All in all, I am very pleased with how it came out.So was the cattle-dog.
