I was a little worried about clamping to the freedom too rails. I try to keep the ski box pretty light. Chairs, tent and foam mats only. The whole setup dismantles off the Jeep in like 5 minutes, so I can go back to a normal roof pretty quickly.Looks like a great setup!
That said... Suggest caution when attaching a rack to the freedom panels. The aerodynamic lifing forces on the freedom panels at highway speeds can be extreme. I doubt that the freedom panels were designed to support these loads since Jeep recommends putting the racks on the back portion of the roof.
