Tesla Model X Towing 5,000-lb Camper: 600-Mile Road Trip

This hasn't been mentioned yet - but wonder if constant heavy discharge, followed by fast charging, will take a toll on battery life. Much more so than an IC engine running high duty cycle.

I'm far from anti-EV, in fact, I believe 99% (not an exaggeration) of commuting should be done with EVs.

But the fact is battery technology is not quite there yet to support heavy duty-cycle. The motors are, and have been ever since GM introduced the first diesel-electric locomotive. 99.9% of rail freight use electric motors for motive, the <.1% being heritage steamers.

As soon as we have reliable 1,000 kwh battery packs, with negligible Peukert factor, then bye-bye ICs.

It does, more so near fully charged or discharged. However, most users have home chargers that do overnight charging and I suspect that many commercial uses will do the same. Tesla seems to be less affected than other brands by battery degradation and is working hard on "million mile" batteries. That would probably mean around 80% of new capacity at one million miles. That is a lot of miles, even for a commercial vehicle. Speculation is that they are already there and are just saving the announcement to make the battery day presentation more exciting.

We should know in about 8 weeks.
