Will, my truck is a 2008 GMC with a Reese slider. The hitch was on the 2nd highest hole and I had approx. 6 inches clearance around the box. But the mor/ryde pin box is long, and the back seems to be lower. The problem is when you are on sloped ground it might hit the top of your tailgate. When I used the slider for the first time it moved back fine, but when I started to back at an angle the back of the pin box hit the top of my tailgate. Consider leaving your hitch at the highest setting. I raised mine yesterday, and the addditional 1 inch should fix the problem. Also, I have found that since the mor/ryde pin box is longer I don't need to use the slider.
