Why is this (the European/Norwegian ball hitch for the Model X and a standard part from Bosal) (Thanks to Bjorn Nyland): compatible with these tow hitch rules for the US Model X: The European ball hitch clearly violates the 3/4" ball offset rule in the US manual. Did Tesla put a different Bosal hitch on the European Model X? I suspect not, but I don't know for certain. I'd love to see the towing section of the Norwegian Model X owners manual. Maybe by comparing that with the US manual, we can get more understanding of the US limits & their assumptions.
