Has anyone used one of the suction cup rollers that attach to the rear window or to the roof for loading kayaks from the rear? I use a Hullavator for loading my 17 1/2' sea kayak but typically carried a second kayak and sometimes a 3rd kayak on my Outback. I now have an Ascent and the roof racks are about 4" higher than they were on the Outback as well as the roof racks being further forward on the rails making getting the additional kayaks harder to get onto the saddles. I use the Yakama SweetRoll saddles for the 2nd kayak. I am wondering if using Seattle Sports Sherpak Suction Boat Roller or similar will work in keeping the kayaks off the tailgate deflector and or roof till the bow gets to the SweetRoll. if that will work I'll probably replace the J Racks with another SweetRoll for the 3rd kayak. All our kayaks are 16'+ Seakayaks. I searched the Forum but didn't find anything so if this has already been discussed I apologize.
