If you use a McHitch coupling to tow with, or are considering one, you need to read my post on 11 November 26 under Warranty and insurance issues if you replace your towball. It detoured a bit from its insurance intent and now covers the problems with the McHitch coupling.
I am restricted from discussing a legal case I undertook in terms of who it was against, and the outcome, but I can share the learnings about the coupling that came with the new camper and was at the heart of, but not all of the problems. Ignore most of the response posts, but particularly see my post on 13/11/26 at 11.45am which includes an attached copy of an engineering report used in my case. It explains why the McHitch is a problem. In short, my VASS engineer documented his opinions for the Court and said the car and camper combination when connected with the McHitch is not roadworthy in Victoria as it increases the load on the tow vehicle.
