Hello, I am sure this has been asked/answered several times but... can't find. Has anyone found a solution to install a european trailer hitch system on its Tesla. I would like to carry my Thule Bike system on a "Trailer Ball" (Boule de Remorque). I know in the US they have the Ecohitch system but the connection part (square opening) seems different than the European one (ball). Also, can you recommend a specialist for mounting the system. Thanks a lot for your help, David, Wavre, Belgium.
