I'm selling a Thule 628 Rooftop Cargo Carrier.
It will hold 3-4 snowboards, 6-8 skis up to 173cm, and LOADS of camping gear for that long road trip-16 cubic feet. A nice feature is that you can load and unload from either side. Both sides lock securely.
The Diamond-Textured AeroSkin Lid is durable and has an aerodynamic shape for less drag.
The tool-free quick-grip mounting system allows you to mount it, and remove it quickly, and easily.
