This is a custom built steel bed rack designed for a rooftop tent. It was built for a 2018 GMC Canyon with a 6 ft bed. The dimensions are 54.5" wide clearance between bed rails, 60.25" overall width, 70.25" long clearance inside bed/tailgate, and 13.5" high. This would probably not work as a ladder rack or kayak rack without modification because it doesn't clear a typical cab height. However it provides a great compromise on volume remaining in the bed and not having the tent up so high that it ruins your fuel economy. I dug up an old picture of the rack and tent installed, but this sale does not include the clamps or tent shown in picture.
You must pick up, as it does not fit on my current truck. Located in Helena near downtown.
