Hi Keith!
As long as your 2018 GMC Sierra 3500HD with the 6.6l Duramax and single rear wheels has the 8' bed, the Pace Edwards Switchblade Retractable Hard Tonneau Cover - Aluminum and Vinyl - Black # 311-SWC96A18. If you have the 6-1/2' bed, you will want the # 311-SWC95A17. It's the same cover, just shorter.
Good choice with the Switchblade as well. I've had one of these on my Silverado since 2018 and it's still holding up quite well. One thing to note though, don't shove a bookcase into it when it isn't opened all the way. I sorta kinda did that and now it needs a bit of finessing to get it opened all the way. It still works perfectly fine and I definitely still like it, but don't do what I did. : P
What are you keeping in your bed?

Hey Keith, how did the Switchblade tonneau cover work out on your Sierra? Your feedback could really help others choosing between the two bed lengths.
