For those that are interested in what else to take for your Model X travel kit for long trips. I met with Rush the owner of TucsonEv (J1772 Adapter | Home) and had him make me a J1772 extension cord. I had him make a 5 foot with the tesla plug (see picture) and a similar but longer 20 footer. The 5 footer cost $175 and the 20 footer cost $215. Both came in handy during our trip to Tucson which has no super chargers. I didn't have to fumble with the tesla adapter and was able to charge if a ICE vehicle was blocking EV charging space. Rush was a great person to talk to and great product. I have no business connection with him.
PS: the auto charging port opening function does not operate with these extension cords
