What do you guys prefer? I've only ever had a standard clamp type ski rack on my car. I just had a roof rack installed yesterday on my wife's Ford Edge at Rack Attack in Framingham, MA. I have ski racks already, just debating if I should consider picking up a cargo box, like the Thule Evolution 1600. I didn't realize they are so expensive ($500 new!!). I think the cargo box would be particularly useful for things like camping in the summer but how much more can you really get in there on top of your skis and poles?
