My 05 was shipped without a tonneau cover. I don't like the idea of leaving anything in the bed uncovered and easy pickings for a thief. I found this low profile cover and installed it on the truck. I like the fact that it does not alter anything on the truck and can be removed leaving no signs it was there. I had to shim the wing up a little, just used some washers between the wing and bed rail. The tonneau cover will not open with the wing on, which I like.
