04 Black, 05 Black, 05 Aqua Blur, top secret can't say anything about another one
I have stood on mine while cleaning the truck so I know they will hold up to 200 pounds no problem. By the size of the brackets they should be able to take much more then that. I don't use mine when getting in or out. I like them because it makes the truck look lower and it helps to keep the truck sides cleaner. The 05 came with them in the bed and I put them on for the trip home to try to keep it cleaner. My 04 did not have them when I bought it but it was one of the first things I added to it. Right now they are off to be painted.
