I have a dually and it is tight. I didn't like being " that guy" that everyone watches the numerous times backing then pulling forward and backing etc ( then throw the dear wife in for a spotter for more entertainment lol ) I used to have a tonneau cover on my truck prior and i left the left lock plate on. My tonneau has locks on both sides and took the right one off. The plate sticks out about 1 inch. I line that up with the metal seam on my camper side that runs parallel to the bed and viola works every time. Never crooked or rubbed fenders :). Prior to putting that plate back on i was always having to take 3 or 4 stabs at it and more then once rubbed my rear fenders on one side or the other.
