Might be kinda "out there" But I have a rolback G2 on mine. Its not anything like the ones that you guys are talking about. BUT I love it and it looks amazing, keeps the water out, and your able to open it anywhere on the rails. Not to mention roll it up and put stuff in the back thats over the height of the box. I don't know if that what you are interested in, but I love the look of that on my truck, plus its user friendly. ???

 

I have the ******* on my 09. I am not that satisfied with the cover. In my opinion it's extremely heavy and hard to open. even though I gave them the paint code for the Stone White, the color is off. Mine was suppose to ship with the brake light, when it showed up, no light. They sent me the light with a cutting fixture, but the wiring solution for a after install is unacceptable to me.
This is just my experience with *******, yours might be different.

 

The leer 550 is flush and looks really good.

 

Look up the Undercover brand, I love mine.
