As for rear bumpers I've ran with out for a while. I will eventually get something on my truck. But the main purpose is to carry the weight of a 35" spare tire. I don't like that tire hanging on the back door. I know it holds but I would feel better with it supported my a bumper, not a door. I like the way Johnnys bumper sits. I would be into something similar if I can put a tire swing on it. Simple and high up. Looks clean too.
