As a quick follow up... the videos actually shows you what you need to do. Installation with just myself took about 4 to 5 hours. I wont be loading this rack with a ton of gear. Only light cargo and accessories. Nice product overall. The hardest part is learning how assemble the mounting points, but once you figure out 1, the other 3 are easy. Make sure you use the foam it came with so you have the rack float on the roof while you assemble mounting hardware.
