Tesla posted a video on how to hook up a trailer to the Model X. One problem. Looks to be a drop offset which the specs specifically say is "not allowed". Here's the hitch on the video: And here's the specs on the Bosal hitch receiver: So for those of us obsessing over hitch heights, offsets, hitch ball holder lengths, etc....there is wiggle room. Which is good to know since I decided to go 1.75" rise on my hitch ball in order to be at the trailer recommended towing height. *I think the closer you get to max tow and tongue weight the less wiggle room I would assume(the Casita in the video is probably only about 2500 lbs and 250 tongue weight).
