Wrong Vehicle combination. If that had been a Ski Boat (would be low and the hull aids flow), he probably would gotten the advertised range.

Driving an EV for range, requires a driving style change. That was rammed home when I rented a car similar to the one I owned before my Leaf. My best mileage before EV was 30 (1.7L engine) After EV was 50 (2.0L)
Simply by NOT using all the performance (snappy starts and quick stops) it had.

Sorry to disagree but from the pictures of their mobile home hooked up to the 3500, it is considerably taller than their 3500 so while the air resistance might be lower, it's not that much lower. I went out and checked multiple reviews/comments/etc. on towing and EVs. Virtually every comment on towing using an EV whether it be a Cybertruck, a Rivian R1T, F150 Lightning, whatever suggests that towing using an EV is not going to be a happy experience. One item compared towing using a F150 in both the ICE and EV versions. Oddly, the Lightning did even worse than the Cybertruck in terms of range loss. The F150 ICE lost about 15% of it's range by comparison.

Has anyone explained why?

I learned a lesson towing one of those box trailers with my F-150 (the gas one, not the EV). I'm not a trailer guy, and this was a one-time tow across the country to help someone move.

Air resistance makes a big difference! Nobody told me I wasn't supposed to drag that trailer along behind me at 90mph. I didn't figure that out until after the trip. Meanwhile, while ON the trip, my gas mileage was about 7 mpg. I could barely make it from gas station to gas station. I was later told that if I had managed to constrain myself to 60mph and under, I would have saved several hundred dollars - or more - on gasoline during the trip.

Oops!

They got about 150km/94 miles from home before having to hit a charger since the Cybertruck had dropped to ~8% charged. At that point, they charged to 90%, turned around and headed home. Once they got home, they hooked the mobile home up to their Dodge 3500 and headed back out.

I have a Chevy Volt and it baffles me that PHEVs didn't take over.

The Volt gives me 50 miles on battery which works for about 90% of my day-to-day driving. But it also has a gas tank which gives me 350 miles.

It might a cube law? 3 times faster needs 27 x more energy?
Even square law would be 9 x more energy at 3x speed.

But the shape of trailer, "tractor" and spacing between them acounts for a lot which is why birds fly in a > shape at a particular spacing.

Air drag for 3x speed requires 9x power and 27x energy for fixed time and 9x energy for fixed distance

At 90mph air drag dwarfs rolling resistance but it is 3x 30mph and increases linearly with total weight, so higher total weight would take more energy even in a vacuum.

mpg also takes a big hit if there is a lot of climbing, even with regenerative braking, and if you run out of juice before significant descending you don't even get that.
