I love the way Andy and Mikes bumper is designed, but just think of the damage of the bed if you was to be rear-ended without a bumper that dont wrap around the body lines of the truck. That was my main concern when building one. Plus imo it would be easier to incorperate a reciever-style hitch on a bumper that sticks out a lil bit rather than just having a hole to put a ball in.
Heres mine I just got finished with a week or 2 ago.
See how it wraps around the entire bed? Id almost guarentee that if someone ran into the back of me I think this bumper would keep the impact on the bumper and the frame mounts rather than someone plowing into the bed.
With all the supports running throughout the entire bumper Id hate to see the damage if someone were to hit me in the rear.
It was so much easier finding a way to incorperate a hitch into a bumper that had a nice, flat bottom plate to mount the receiver hitch. Note all the gussits that support the receiver. Id feel confident pulling anything that I could with my factory hitch.
