Been quite fond of Line X. Ordered my new truck with the Black Appearance Package, which includes the factory spray in liner. It seems fine in comparison to the Line X, but the attention to detail is lacking compared to my Line X dealer. I could see that maybe being installer specifiec though. My local Line X installer removed the box link brackets (like mentioned above), and I believe they also removed or taped off the bolts to mount the bed. They also didn't get overspray on the body of my new truck like Ford did. Knowing what I know now, if I had a choice, I'd probably go Line X, if you know your local installer is good. I'm sure not all of them are created equal. Wouldn't have mattered in my case though, I wanted the Black Appearance Package, and that's part of it.
