Rather than buying all of the parts necessary to make your regular truck rack into a double decker truck bed rack, why not just buy it that way. This is where the TRUKD Double Decker Truck Bed Rack comes to the rescue. Specifically, what this creates is you add the 24- inch TRUKD Truck Bed Rack, and gives you two additional cross bars with brackets! This is probably the best setup for your rooftop tent if you have a lot of gear, since you double your storage space by offering an additional layer between the top of the truck rack and the box of the truck bed. This truck rack works with a soft roll-up tonneau cover. Make sure you have room for everything on your travels with the TRUKD Double Decker Truck Bed Rack!
