Well its about a year late replying, but, to Chuy: The nerf bars function just fine, I haven't had any issues with them as far as reliability and wear and tear. They allow you to access the roof easily, and the Steelcraft models look good on the car and integrate well with the shape of the side panels.
A few drawbacks are the rubber steps have faded in the sun, though I do park outside almost all the time, and I have not tried to restore them. Also the brackets holding the bars really reduce your ground clearance, they seem to hang much lower than seems necessary. The bars also make it hard for short legged folks to get in the car. No problem for me, but my gramma not so much lol. Mostly tho I want the change simply for aesthetics. I like the look of the factory side steps better after all.
