because THESE boards look really great... they add to my truck look instead of degrading it... although 500 pound limit... that may be across the length and not in one exact spot, so if you are using this step board to unload stuff from an over-cab roof rack... think about how much you weight and how much the stuff unloading weights... combined... otherwise, if you are not using THESE boards for work and just want to get in and out of your truck for casual occasions... they will last forever looking great...
