The people who I dealt with are fine, but a little misinformed of what will work with my particular vehicle. I ended up buying Wingbar Evos that were 3" longer than Thule's recommendation so that they would accommodate a pair of Hullavators. There is a set of pictures on Rack Attacks web page that show this setup on the same vehicle I have. In actuality, the bars are too short. The Hullavators will function, but are so close to the side of the vehicle that they will bang the side of it with a kayak on the rack, ready to load. They should be 3 " longer. Rack Attack exchanged for the longer bars. I realize that this isn't entirely a Rack Attack issue. Thule is just really bad at providing guidance for applications. I've received much poorer advice from vendors other than Rack Attack in the process of trying to get the Hullavators mounted.
