Even today, professional reviews (meaning Motor Trend, etc) of electric trucks such as Rivian conclude that towing a trailer will cut the truck's stated range more or less in half - depending on the weight of the trailer, of course. So if the stated range of a bare truck is 400 miles, you can expect the range with a trailer to be on the order of 200 miles. Beyond that, there is usually no mention of the fact in the world of electric trucks, as in the world of gas or diesel trucks, "stated range" means fully fueling the vehicle, then driving until you run out of fuel. Of course this is not practical in the real world. I usually begin looking for fuel when the gauge drops to 1/4 or so. So if the bare truck has a stated range of 400 miles, its useful range is 300 miles, more or less, especially if you are out on the highway where fueling stations may be far apart. And that makes the practical range of the electric truck with a trailer 150 miles or so.
This is a significant handicap in my mind. This will be a tough hurdle for the industry to overcome. Today, electric trucks have significant towing capacity - but not for very far.
