Total - 590 Wh/mi (11,592 miles tracked by TeslaFi; missing a couple hundred miles pre-signup)
Not towing - 402 Wh/mi (5,706 miles)
Towing - 773 Wh/mi (5,885 miles)
Here is a selection of various trip legs with more details. It's not easy to draw any straightforward conclusions, and I think Teslafi gives the average MPH based on distance divided by drivetime - so if you are sitting at stoplights for half of the drive, and driving 100 MPH half the time...

The CT does charge the trailer's batteries while plugged into the 7-way plug.
I do have 100W of solar on the roof of the airstream, and I hauled around an Anker SOLIX F3800 with 400W portable panel, and I have some bigger (not "portable")...
I did use Teslafi - let's see how this roadtrip sharing works:
SLC to Houston - Cybertruck dual motor w/ 19' Airstream
Looks like Teslafi says I paid more for supercharging than I expected, since I did charge some off the Supercharging network.
Yes, if charging at home. But supercharging cost ~$0.33 per kWh, so the entire drive would have cost $886 at supercharger prices - I think a truck getting 13 or 14 mpg would have come in at a similar cost for gas.
It's NOT a better tow vehicle than other trucks, at least on time and money...
My speeds varied - on the highway I'd usually cruise between 55 mph and 65 mph, with higher speeds really hurting the efficiency. I had a headwind in Wyoming which destroyed my efficiency, and I ended up driving 49 mph just to make it to the next supercharger.
The "Energy" portion of the trip...
I took my Cybertruck towing 19' Airstream (~4,500 lbs) to see the eclipse. Total towing miles was 3,400 (out of the 5,400 total miles on the truck). Started in Salt Lake City, Utah and went to Houston, TX and back.
