Rear bumpers for pickups used to be an option. My father opted out when he bought his '75 Power Wagon, then welded one up from a heavy piece of 7" I-beam. Funny thing, he never had problems with people tailgating.
When he sold the truck my cousin put the bumper on another Dodge, 2WD. One day he was spinning on a hill at a stop sign so the 18 wheeler behind him came up and nudged him just enough to get the truck moving. I wouldn't advise that with a new pickup.
