Leaving a roof box on your vehicle on a regular basis could cost you big and if you need it often, maybe it’s time you look into getting a bigger vehicle. Installation mounting hardware requires no assembly and fits car rack systems with round, square and most factory crossbars. Perfect for snowboards, skis or a weekend’s worth of gear.
That said, roof boxes that aren’t completely necessary are costing you and the environment. 11 cubic feet (89 x 22 x 14) Nice size, but it won’t hog your crossbars. Many also now allow you to swing the crossbars of the rack lengthwise when it’s not in use if you have that feature, use it. Some original-equipment roof-rack designs are better as they were designed specifically with that model in mind. Even though they might look like they ‘cut’ through the wind, they could be introducing some mileage-robbing turbulence and drag on the highway. The same, of course, applies to roof racks and other cargo accessories. favorite this post Jul 10 specialized motor bike 250 (Yakima) pic hide this posting restore restore this posting. favorite this post Jul 10 mouse hunters 40 (South Cle Elum) pic hide this posting restore restore this posting.

Adding any roof box increases frontal area of your vehicle, of course but no matter how aerodynamic it might look, it also alters the flow of air around your carefully shaped, wind-tunnel tested vehicle-creating drag and turbulence that can, together, knock 10 mpg off the mileage of a smaller four-cylinder vehicle.
