I had the Superglide on a 15 SD. I had the B&W hitch so I had to install the additional mounts at the rear. Required drilling two more holes in the bed.
When I sold the truck I sold the Superglide with it. I had several issues with it. One, when the handle retracts that does not mean that the latch is latched- even though its supposed to. Twice I started to pull out and it wasn't latched. Second issue was as I backed into to the hitch the pin bent the little swivel arm that stick out. Third its hard to get it to unlatch, you have to "jig" the truck back and forth. Lastly you can't unhitch at much of an angle.
On my new truck I use the B&W Patriot. It's a manual slider but have had no issues.
