Have the 6.5 ft bed on our 2500HD and have a slider hitch.....reason being, I have a tri-fold truck bed cover that I let ride propped up on a slant above my TrailAir pin box...even though my front cap has the indentations in it for tight turns, I still get into my bed cover......so, I have to manually slide my hitch 10" to allow for clearance on tight campgrounds.....using a Reese Pro Series 16K.
