I have a Rhino in my 2003 F150. I had it installed back in 2003. It has faded from black to gray and the truck is mostly parked in the garage. I went with Rhino because the installer is just a few miles down the road where as LineX is about an hour away.

The Rhino has held up well (besides the fading) and have had no issues with it. My next truck will probably have LineX and a cap.
