I have an ATV rack made for an 8 foot pickup bed. The wheelers sit sideways on the rack. I hauled two 2015 and 2016 Polaris 570 sportsman's on it easily. To be completly transparent i do not believe some of the newer larger wheelers will fit on it. Some of your smaller ones will but not the big boys. It has 12 foot ramps so its not too steep for a truck with 35" tires but the taller the truck the steeper the climb. This rack was custom built and does not rattle when empty on dirt roads. Its a very solid rack. Come take a look and make me an offer. I just don't haul as many bikes around anymore so it hasn't been used in a year.
