I can't believe it. I just got my new Companion slider unboxed and went to set it in place with the turnover ball hitch and it failed to seat all the way. Now I can't get it back out. Man this thing is heavy too. I plan to go back to the shop that ordered it for me and see if they can pull it back out with the forklift. I guess I am learning a hard lesson on cleaning the socket out good and lubing it before installing.
