I posted this to the Model S forum a few weeks ago and am still trying to determine what to do. I am seeking some input from my 'neighbors' as you might have a good sense of local solutions and shops that can help me here. I am trying to determine the best way to carry bikes on my car (I prefer to use a rack and not dis-assemble the bike and put it inside the car) and am considering the roof-top rack from Tesla (which I could also use for carrying skis) or the Eco Hitch (which would allow me to attach the Yakima carrier I already own.) The closest Eco Hitch installer is about 125 miles from my home (outside of Baltimore). I welcome input on this decision.
