You've chosen to get a super tough Westin cargo rack, and whether you chose the reliable Sport model, the tougher, adaptable Outback, or the heavy duty, contractor grade HD version, you've got a superior cargo handling device that will serve you well and handle the load. That was a great decision, but now you've got another one to make, because this company gives you a number of mounting choices to suit your particular needs. You need a Westin Cargo Rack Mounting Kit, and if you want quick installation with no drilling, you'll want the gutter mount configuration, which you can also remove if you want to. The track mount kit is more permanent and solid, and you do need to drill to put the tracks in place, but then you've got a system that allows you to move crossbars around at will, so it's strong and adaptable. The fixed mount kit gives you a universal fit system that's perfect for truck caps and steel roofs, and its support legs mount directly to the roof or truck shell, so you've got an extremely strong support mechanism.
