Tell me more about this, if I'm not mistaken, james actually started his bumper off the same fashion and made it an air tank as well. (3x6) doesn't say shit.
Nothing to see really. I don't care for the rear bumper to be removed then the basic shape retained with metal. I was able to cut the stamped upper away from the reciever by cutting a right angle on the arms that bolt to the frame and lay the 3x6 on top of the receiver. it's strong.
