Today, after long last, my excruciatingly boring posts about potential Model X trailer dynamics are over. At this point, I will begin with a different variety of snoozers - data-driven Model X trailer dynamics posts from my own experience. I drove over to Fairfield, CA this morning to pick up our Airstream 22' Sport. Please excuse the fact that the photos look identical to @JimVandegriff's awesome rig, but you can't help good taste. Delivery went relatively well. The fit and finish issues on the Airstream are worse than they are with Tesla. And Airstream has a very good reputation in the RV world.. so deduce from that what you will. In general, the coach looks great, though. We got our Equalizer weight distribution hitch installed without much issue, and after a walk-through, I was on my way. The first data pieces - my drive to Fairfield was over hilly terrain in very gusty conditions. I didn't bother with curbing my speed and probably averaged 65mph while reaching as high as 75mph. 30.7 miles, 307Wh/mi. I didn't fudge those numbers to make them a multiple of ten. Also, those numbers clearly represent a tailwind based on my average consumption. That means headed home, I was trailering into a headwind. On that journey, I averaged about 55mph, with a max of about 62mph, and along the way I consumed 582Wh/mi. Generally speaking, that's just about what I expected since @JimVandegriff has consistently reported around 575Wh/mi at 55mph. It was my first time towing anything, other than behind my compact tractor, and while it definitely felt different, it was comfortable. I set my brake controller at a very low level so that I could recapture as much regen as possible. I was really astounded by how much the regen could slow down the trailer/Model X combo without trailer brakes engaging. This is an area for definite attention, as I think it has some potential for extending stop-and-go range. The X could accelerate without issue. I'm not surprised. I generally tried to drive like there was an egg on the pedal, but a few times I wanted to see how quickly I could get up to merge speed. It's absolutely not a problem - on the Model X, range is constraint when hauling an appropriately sized travel trailer. There is more to come. I am intending to post to this thread when we have outings in the camper, and supply consumption numbers ad nauseum. Until then, here are some photos from today.
