Looks good. I cannot speak to the LED adapter, as I have one and always use it. My X is over 3 years old, though.
So we've just returned from a short getaway with our June 2017 X100D and the 2019 Airstream Sport 22' that I rented. I'll start off by saying that we absolutely loved the experience. It was out first time towing and we thoroughly enjoyed it. Without all the precious advice we got here on TMC from ohmman, jimvandergriff, mengwong and others, I'm quite sure it would not have been that way so thank you all. In the spirit of giving back, I wanted to share some of what we experienced.
RANGE
As it was our first experience, only had a few days and had to head back home to drop off my significant other and pick up the teens half way through, I kept the distances to a minimum (around 400 miles total) which means charging was not an issue. We visited two different campgrounds where we stayed long enough to charge on 15 amps. Only once did I have to use a SuperCharger and block a few stalls. Luckily, it was not busy. See photo! In terms of the impacts of the trailer on range, I can only say ohmman and jimvanderriff are bang on. At highway speeds, I lost between 40 and 50% of my rated range. Note I rarely went above 60-65 MPH and spent most of my time at 55-60 MPH. On country roads, it was closer to 30% on flat surfaces.
HANDLING
I chose to hitch with the OEM receiver and, as advised, no sway or WD system. Frankly, although I cannot compare having never towed before, we did not notice significant sway. I never felt unsafe. I did, however, notice some wobbling when going over bumps at higher speeds. By that I mean the car's front and back ends going up and down slightly. As you'll see below, at one point, stability control on the X got disabled. During that short time, oddly enough, I did feel more sway and less wobbling. Could be just be my perception but that would be logical as I understood trailer mode adjusted braking and stability control to minimize sway. Again, I have no prior experience. That being said, I did not experience anything that would not make me want to try that set up again. I haven't removed the receiver yet. Will inspect it and report back after I have.
ACCESSORIES
The LED lights of the Airstream worked fine, no adapter needed though I had the TowReady one just in case. I only had one glitch which I believe was related to the 7-blade connector. After going over a train track and tough pavement around it, the X started giving me a number of errors (ABS, stability control, regen, autopilot, etc. disabled - see photo). Stopped by the side of the road and noticed the 7-blade connected was slightly unseated. I unplugged the cable and noticed the trailer icon was still showing in the dash. Powering off completely cleared the icon but not the errors. Drove a while and the errors remained. Only when I stopped again, unplugged the brake controller, unplugged the trailer connector and powered off the car did the errors go away (also tried the famous reboots to no avail). I believe the loose cable caused some sort of short which freaked out the car and a full powering off was required to clear the errors and that the first time, I didn't really power the car off as the brake controller was still plugged in. Just a theory but I will DuckTape that cable next time!
I also had HaulGauge to measure tongue weight and weight distribution. Although it did correctly measure my body weight in the trunk before getting the Airtstream and tongue weight when trying out a Uhaul trailer to practice my backing up skills ;-), I could never get it to work again the two times I tried when hitching the Airstream for some reason. In both cases, it gave me no reading in the app. And because I was on a busy road picking up the travel trailer the first time and then under heavy rain the second time, I didn't play with it too much. I plan on trying again next time I hitch.
Brake control was through the Prodigy P3. Worked fine in the X. Had it at 5 power level but propably could have gone down to 4. No boost. Did not notice it sending brake voltage when on regen though. Thought I read somewhere on TMC it would.
AIRSTREAM
We've always eyed Airstreams. Towing and camping in one finally was a blast. It did not disappoint and provided the experience we hoped for. Noticed some of the fit and finish issues reported by others. Small stuff really that wouldn't hold us back from buying (but at that price, like Teslas, you expect a higher quality I suppose).
Now our dilemma is the following. We know the 2019 22' Sport provides the sweet spot in terms of space and weight for us electric towers. However, while comfortable for 2 and then 3 in the second half of our journey, we're not sure about it for our full family of 2 adults and 2 teens. Would seem tight, especially that dinette bed. I guess we could ship the kids to a tent... There's also the reality they likely won't follow us for very long still!
We also wouldn't mind some of the extra amenities of the Caravel series (quieter AC, better stove, etc.). So, we're now debating grabbing up a 2019 22' Sport or swapping up the OEM receiver for the Draw-Tite allowing us to bear the Caravel tongue weight (would never even consider exceeding that with the Bosal receiver). Or, we wait for the Tesla pickup and get a 25' Flying Cloud. ;-) But something tells we wouldn't be camping in the near future... One thing is sure, we want to camp and do so in an EV.
Anyway, thanks for the advice all and hope some of my experiences are helpful to others. Happy to answer any questions.
