Take-away. The CyberTruck tows great...but not very far.
Those that want/need to often tow heavy loads for great distances will still still be better off with a heavy duty Diesel truck.
CyberTruck will work in a pinch, but you need to consider short range and stopping every 100 or so miles to unhook and charge up.
Booster battery in the bed might help in some circumatances, but big Diesel is still the Pickup heavy duty champ.
I have towed 2,000 lbs in my 100 kWh Model X. It did amazingly well, but I was only going 150 miles or so, and stopping at a SuperCharger once was no biggie, as I had lots of time, and it was far easier than renting a large pickup for the task.
EVs work great for casual recreational towing, like taking a boat or jet skis to the lake. Also good for towing a camping trailer to a nearby campsite. They have an amazing towing experience as you are in a non-smelly, quiet, and powerful vehicle with good electronics.
Just as trying to use a CyberTruck to provide heavy duty, long distance towing, is perhaps an inappropriate choice, it is equally foolish to chose a huge truck, with a large towing capacity, to commute to and from work or running around...yet many owners do just that.
