I used the term "expert" and in quotes as I am at a loss to recomend a person or place to get the pin/pin box inspected. Could be the OP's dealer, but I have never been to his dealer and I do not know what the OP's confidence level in his dealer is, but depending on the circumstance it could be a place to go to. It could be a place tha.t sells and installs hitches, but again I do not know of a particular place to recomend to the OP. To me usually a place of business that acepts money for services rendered, which has been in business for a while with a good reputation would be considered an "expert"!
