Just found out my MX 75D that I took delivery on Sept. 29th is missing the tow package. I thought tow package has been standard equipment since the end of July?!? is anyone else with recent delivery missing the tow package as well?
See my post here on missing tow package on recent deliveries. Towing...actually Airstreaming...with a Model X
Also you can read up on possibly related issues with the Tesla/Bosal system in related threads, like ones from @ohmman who has some good videos on the subject.
