I have the same setup (full swing with tram). It does the job but is very large, skis do get very dirty, and the ski rack is pretty difficult to load multiple sets on as you kind of have to hold them in place.
Does anyone know if there is a way to get the Tesla to know there is an accessory rack on the back though? Trailer mode disabled too much. But without trailer mode, the car frequently thinks there is a car or bike or person or motorcycle behind me. Autopilot still works but I worry it will someday cause the car to overreact to something it perceives is behind me.
