Not for the "v" -- but I'm VERY happy with the fit and finish of the Thule "Aerotech" rack I recently installed on my Gen II. I suspect if they don't yet have mounting towers for the "v", they will have shortly.
Found one! Rack outfitters is selling it for $380. Plus they have installation videos on YouTube. I apparently need 2 more posts before I can post a URL....

I picked up the Inno Boardlocker, but haven't decided on a base system. My question is, what do you do with the key-fob as you can't take it in the water with you.
