I just picked up my PA two weeks ago and loaded it on top of my Toyota Highlander. I used the Yakima Mako Aero Saddles on the front bar, Hulley Rollers on the back bar and the Showboat to clear my spoiler on the back. The Toyota factory rack is rated for 165 pounds, so I'm close to capacity, but I think OK. The Mako Aero will definitely work with the factory crossbars. You'll need some Mighty Mount adapters to mount the Hulley Rollers to the factory crossbars, but they are a breeze to install. The Showboat using the 66 inch bars was a great investment. It makes loading very easy. I do have the the Showboat fully extended (maybe slightly overextended
) to clear the spoiler and it does flex a bit and contact the spoiler just slightly when the max weight is on the Showboat for a few seconds, but I don't think it's anything to worry about. I might get some heavy foam pieces to wedge between the Showboat bars and the vehicle roof, just behind the spoiler, to provide a bit of support and prevent contact with the spoiler when loading. The PA is a big wide boat, so the Saddles and Rollers will have to be set fairly far apart. Once I made adjustments to get the best fit and strapped the boat down, the PA was completely solid on the car. A good rack that makes the PA easy to load and use is a great investment. It would be a shame to let loading difficulty keep me and my PA off the water. I can't wait to get started. Go away snow!
