Hello, I am an avid kayaker and needed to carry it on top of my Jeep Wrangler. I designed and am having manufactured a rack that does not interfere w/ any of the jeep tops and is capable of carrying kayaks, small boats, and basically any other form of outdoor equipment (ie, skis, snowboards, windsurfer, etc.). If you want more info you can email me @ mnphares@hotmail.com. Look foward to hearing from you! Best Regards! Matt
