Shopping around for crossbars to mount to the factory rails. Owners manual says you can put 200 lbs. on the roof. Yakima racks at $155 have a limit of 125 lb. Thule racks at $190 is 165 lb. Not sure what the VW racks at $165 can hold. Anybody have an opinion on this one? I would use them for the occasional oversized item(s) that would not fit inside.
