My Chevrolet Bolt actually shows me the real-time kW draw from the high voltage battery and, while it's highly dependent on driving conditions, it seems to require around 12-15 kW to maintain 60 MPH on a flat dry road using cruise control and with the climate control turned off. It's not the most efficient model on the market, but it's also far from the least; as you noted your F-150 would need significantly more energy under the same conditions.

The lightning is ridiculous, it weight 70% more than your bolt and is huge.

My partner and I honestly bought it to be a whole house backup battery. My regions get ice storms and we have hundreds of gallons of aquariums we'd need to keep powered through a long duration power outage. 135 kwh of battery storage cost more than the 135kwh battery truck, so we got a whole house battery backup system with wheels and cruise control. It can backstop 80 amps for 3 days.

For what it's worth you get fairly similar results if you assume an efficiency for a ICE engine (25-40% depending on a lot of things) and work backwards from the energy density of the fuel and the milage you achieve over a trip.
