It has the ability to pull the trailer with ease, but most preliminary estimates are that range would be two digits with that sort of load. In my current vehicle I do stop for gas midway, but it would be an entirely different situation hoping for a charger spot (with connected trailer) and then the time to charge.
Still a great truck, though. For a huge range of uses, including more local towing situations (the vast majority of commercial uses), it could be brilliant.
And eventually they can market a super-range battery you can tow. I kid...or do I?
