TL;DR - Towing my 23fb Airstream with the lightning basically cuts range in half. I was able to tow the Airstream around 30 miles today and understand how the Lightning does with some weight behind it. The TL;DR is that with a 23-foot Airstream, I am seeing 0.8mi/kWh. Compared to the 1.5-1.8 I have seen on my road trips thus far without the trailer, its around 50% of the range when towing.
