With tow ratings you subtract the weight inside the vehicle. At a tow rating of 800lbs you're not going to be pulling much of anything, and with a 41 kW/h battery it is not going to be going far at all either while towing.

I would love to replace our ICE tow vehicle with an electric if any existed, but the electric range would drop by at least half while towing. That's a lot of stopping.

As a comparison a v6 Dodge Durango's tow capacity is 6200lbs/2800kg. A v6 tow vehicle is a part-time tow vechile not intended for large loads. That durango can pull some boats and smaller camper trailers. We have used it to haul rock/gravel/stone as well. Electric would be great because the transmission wouldn't be as much of a concern but it would definitely need a lot of battery and would need a larger cooling system for the batteries and motors just like ICE tow vehicles need larger fuel tanks and larger radiators.

For comparison, a 400 kg tow rating you get on a Fiat 500 with the 0.9 L three-cylinder petrol engine...
