I have a 2011 Chevy Silverado 2500 HD. Of course GM stopped putting roof rack bars on trucks a while ago. I just got a Kayak, and it is 14 foot long, it doesn't fit in the box very well, I only have the 6 1/2 box. I was thinking of buying an aftermarket roof rack system, I was thinking of Rhino Rack or Yakima roof rack systems that connect to your drip line and the upper part of the door jam.

Any recommedations or suggestions, let me know.
