I'll take some pictures tonight for you. I think you're going to have clearance problems between the mount that goes AROUND the tower tubing, and the windshield. The tower in the "extra-low" position actually lightly touches the windshield on my boat for ahead of the mounting location. Not a huge ordeal, but worth checking for clearance. I'm also unsure how easy it will be to run wires in this tower. I think the bottom has a solid plate welded in. I'll take some pictures of that as well. To answer your question though, you will definitely have to swing the racks to the interior of the tower to get "inside" the windshield. Same with teh speakers, you'll want those "under" the tower, both for folding and for bimini top usage.
Another thought.....If you know the size of your board, I'll gladly measure the ski locker. I have my 45cm wakeskate in there right now, and there is TONS of room to spare. The racks on the tower are neat and all, but unless you have a ton of boards they are more sizzle than steak for me. All our friends have dedicated wake boats (Centurion 26ft and Axis 22ft) and rafting up is always a PIA with those damn wake board racks having to swung in and out of the way. I much prefer the ski locker storage for our board.
Thanks for the feedback. I've been reading a ton on the Traverse/Acadia platform message boards the last few weeks. Most people say they tow great, and I don't have any reason to doubt that now. So much so that the wife and I are contemplating trading hers in on a new one with a warranty, and making it the dedicated tow vehicle, and I'll keep repairing the PO-SS that I drive. If you see my other thread, we actually tested it out this weekend. I'll go find a link.
