My wife and I have decided to become more active, so we will be purchasing kayaks. I will be using the factory roof rack on my '12 Pro4x with any additional equipment I may need to purchase (cross bars, etc.). The issue is I'm not sure what I need to make it work. I have saw several threads along with pictures of what others have done, but I am new to this and I can't figure what I need. I want to make it safe for 12' kayaks at highway speeds 55-70. The local lake is a 30 min to 1 hr drive from here depending which side you are going to. I also want to maintain the factory roof rack without damaging it in anyway. Could anyone point me in the right direction with pictures, part numbers, etc? Thanks!
