Hi noflash; Yes they are expensive but real good quality and warrantied as long as you own them. I have the boat loader[tadem kayak] which aids me loading the kayak myself. The air deflector as the rack was noisey at speeds. And a long narrow box with built in clamps and lock with hyd. shocks on the door. And the racks for the kayak. All for about $1000. Very easy to remove and re-install. Its just like the car, real good quality, and I like that.
cheers,H
