Back racks are a waste of money and ugley. My friend Jesse has one on his Dodge:
^ It's in the background.
It rusts easily, it wrecks your rear view, it is completely unneccesary unlus you haul bricks or something. All the Brackets for lights are too tall and obviously built for government applications. It is way too simple of a unit with cheap materials to warrant the cost. I would save the money and fab up your own rack instead of buying one.
Just my opinion
