I feel like this is less true nowadays. Or at least, less of a concern.

I have a Rivian and my 400mi range gets cut significantly (down to 200 or 300, depending on the trip) when I have 7k lbs on the back, but never enough to stop me from towing. And with good charging in the area, it's a non issue. And waaaaayyyyy cheaper than diesel.

Maybe if I was towing daily, I'd feel different. Your mileage may vary. (Couldn't resist the closer!)

Edit: btw instant torque is a game changer. You can't beat an EV on that front
