That ball is for a gooseneck trailer, which you won't see used on RV's. It probably means that that truck has a dealer prep hitch package that would allow you to drop some models of fifth wheel hitches right into the bed mounting holes without getting rails installed.
For a bumper pull type trailer you'd just use a ball installed in the receiver on the bumper.

The hitch prep is a 400 dollar option. Then you need the picture frame that mates with the trucks system. Reese has the picture frame for less than RAM. Installing the hitch prep later cost a lot more. So order it or buy a truck with it. Chris
