I’ve looked around and had trouble finding a good shop to install a hitch on my 3 for use with a rack. Neither SD Trailer Supply nor the authorized, but non-Tesla body shop in Sorrento (Amato’s?) will do it. I’ve seen a number of hitches and racks around town, so there has to be a shop or two that will do the install locally. If you’ve had luck with a local install, please post. Thanks!
