Haha! I just did that tonight!
The rear bumper is really really easy. Just unplug two wiring harnesses on the driver side of the bumper, then there are two nuts that you need to remove from the bracket at the frame. I think they are 21mm. Really easy just make sure you have someone to give you a hand lifting it off the truck.
The front bumper has 2 bolts next to each of the tow hooks. I think they are 19mm. Then on the backside there are two smaller bolts holding the angle brackets to the frame. Front one has wiring too that needs to be removed first.
