"The Truth about Electric Towing" - The video author says that weight doesn't make much difference, but aerodynamics does. Towing a big flat piece of plywood that weighs 50 pounds but catches the wind is much worse for your range (or MPG) than towing an entire second truck, if the towed truck is aerodynamic.
He's only comparing highway driving. As he notes, city driving (or really anything with a lot of accelerating) will see the impact of weight on fuel consumption. Seems like regen brakes can help mitigate that for electric vehicles.
Side note, if he set the parking brake when getting loaded then the second tailgate denting might not have happened. It'll also help save the transmission.
Yes, Ford has done plenty of tests as have regular folks, loading the bed to the weight limit of the truck doesn't have much impact at all on range. It's 99% about the aero.
