I don't have a superglide but I do have the superfifth. We bought a bed-saver and the first one they sent us was the wrong model and didn't fit. The took that back, paying for shipping and sent the correct model. OK I thought, they made a mistake but fixed it.
We installed the bed saver and since we had the shipping foul up didn't get a chance to check it before leaving. It turns out it is mounted too high on the hitch and the king pin doesn't clear the bed saver as you unhitch (or hitch) This eventuall damaged our hitch, pullrite sent a set of repair parts but it still doesn't seem to be working right.
Advice: don't buy it unless they've fixed that problem.
