Yeah, the ones that connect via that ball are mounted and stored on the front of the toad. Very few folks are using them now. Those you see are usually a temp install to tow a car one time. Get the one that slides into the reciever. There are many threads on the board that discussed the benefits of different makes. The two most common are Blue Ox and Roadmaster but there are others also. Have fun and enjoy the process.
