Pro Hitch Do me a favor Monticatgeek, please tell your contacts at Clam to coordinate the shelters with the hitch. I recently bought an X200 flip over at Cabelas but they didn't have the hitch in stock so it was shipped to my house. There are holes pre-drilled (or half pre-drilled/started) in the front of the sled in the pattern for the pro hitch. When I got to assembling the hitch, I held up the tow bar and confirmed the holes that were in the sled were correct, they looked like they were, and there is no template in the package for drilling a sled. Problem is, the holes are about a half inch off from the tow bar backing plate. So rather than re-drill the sled, I had to elongate two of the holes to accommodate and that backer bar is HARDENED steel. I know it sounds minor but after assembling the x200 for about 5 hours (that was advertised as pre-assembled and was most assuredly NOT) that was not exactly happy time for me! Just let people know that they need to ignore the pre-drilled indents in the sled and use the backer bar as a template for the shackles please.
