OK thanks, and you probably see where I was going with the question. He tried to pull 1.5 tons with a 0.5 ton payload truck. I am sure it can do it (gas or electric), but, with a lot more energy required.
Payload is basically what can be loaded in the bed over the rear axle. Towing capacity is usually much higher than payload. My friend has a 2019 F-150 with a 10k lb towing capacity behind a turbo charged V-6. His only issue was a pass in southern Colorado that gave him some overheating issues pulling his Jeep on a trailer (combined for about 8,500lbs).
The F-150 lighting should have no issues towing 3,000 lbs with its 7,700 lbs towing capacity.
