I still have it on my Scion XB. Its quite easy to load and unload the PA14 with the Yakima boat loader on the roof rack. The trick is to angle the front end of the kayak just right and lift and sway the PA14 as far to the other side as you can then put the back end of the PA14 on the other rear bar. Dont lift direct straight, doing so will cause the PA to slip off the boat loader.
