I too just bought an Eagle Superlight with the Reese revolution pinbox option installed by the factory.
With this setup I did not need a special hitch for the 6.5' bed on my Chevy.
I trusted my Jayco dealer - he set up the hitch for me and told me what I did or didn't need. No slider - no expensive hitch. We used a Valley hitch and everything has worked perfectly.
On the way home from the dealer we went to buy a better mattress, and did a 180 in their tiny gravel rear loading area with no problems.
The Reese pinbox pivots at the camper instead of at the hitch.
