Road Rhino was the fab shop for Road Armor for a while, from my research I fount that there was a contract falling out some where so they started making the bumpers and selling them themselves at manufactures cost. From what I've read in my research the welds are a lot better at road rhino and they also have the WIY (weld it yourself) option to save money in shipping. http://www./f100/pictures-4636/
look to the bottom picture and see how the front bumper would arrive to you in the WIY option. Over at the ramforum . com Road Rhino is a prefered vendor and they have more info on pricing you can get your bumpers straight from the manufacture the shipping sucks but it's all 3/16" and 1/4" steel can't expect it to be free.
