I absolutely love the black factory Assist Steps that came with Rally 2 package. I feel they give enough footing and aren't too big... I do not think they take away from "clean" look. I am typically not a fan of any side steps, but I think these looks pretty good on the truck.
This might sound weird, but maybe the black 22 inch rims on the Rally 2 package help the black Assist Steps look more acceptable. A nice tire\wheel combo can just about make anything look better (mud flaps, side steps, etc.)
