If it's just cover damage, I would think you have a good chance of bolting something on and getting a good match on a car as new as this. Over the years fading conditions will make things harder. I recently replaced a damaged door and fender off of another truck of the same year and color, and it turned out as well as trying to get it painted and matched. Of course, white is a pretty basic color...
Good luck!
