How long have you had the hitch on your S and 3,
@tpoltron? I know it's a pain to check, but are you worried about galvanic corrosion between the steel hitch and aluminum body? Another poster had to remove his bumper for another reason and found corrosion where the frame contacted the S body. The possibility of hidden damage has me on the fence. I wonder how Tesla addresses this with the tow hitch on a Y or X.
