TLDR: Yes, and you get better mileage from first towing the tesla (using x amount of fuel) and then driving the tesla with this charge thsn from driving the raptor with the same amount of fuel, even though the fuel consumption of a raptor towing a tesla is insane.

What you’ve done is build a hybrid car.
