The range loss on an EV is comparable to the 5 MPG you are going to get with a 3/4 ton truck towing anything 10k pounds as well
The only actual difference is time you need to charge. Pull through charging stalls are ubiquitous where I live
And I just don’t know…how often are people towing loads over 100 miles regularly for this to be a problem? Where I live I see pavement princesses towing the occasional boat or landscapers towing gear and rocks.
Neither of those is going to max out the range on an EV truck in an average day
