This is a complete hitch assembly to pull a fifth wheel type of hitch with a gooseneck ball. It converts in seconds. No holes to drill it connects directly to the ball. This is not the traditional gooseneck adaptor it's a totally redesigned type of hitch. It takes all of the tugging feeling out of it. I used this on my camper for one season. I no longer have the camper so I no longer need the hitch.
