 I put a 2-inch receiver hitch. I went to Wheel Equipment, all brand new. I used it one time. The thing that slides in the receiver hitch and a 2-inch ball, brand new. I had to do one test to make sure we could do something with the guys. I was training the kids the other day on how to do this, and I wanted to use brand new equipment. I don't have the pin that holds it in the receiver pitch, but I used 5-8 bolts, grade 8, made in America, not China.
