I've tried this one - http://www.amazon.com/Lund-30002-Gen.../dp/B000COL4A4
it works OK on the sides and along the side of the rail. I have RAMBOXES, so my rail is a little bigger. I don't like how it fits on the bottom of the bed. The tailgate pushes it down and the sticky tape is exposed a bit, so it's probably going to fall off sometime soon. I'm not sure if I put in a bad spot, but with the way the tailgate moves when you close it, it seemed like the best spot to put it.
