Having too many issues with the 09 F150- The 5.4 that year is proving to be to problematic. I borrowed a friends 3.5L Ecoboost to pull my 5000lb trailer and it pulled with little effort. Looking f...

I have a 2019 Expedition MAX as a secondary tow vehicle for my 7000 pound boat.
Towed a very light 17’ fishing boat back from North Dakota a few weeks back. 75 mph with some wind and I was at 9 mpg. There really doesn’t seem to be a huge difference in MPG when towing regardless of weight.
That is what I have been telling people for a long time, weight only impacts fuel economy through rolling resistance and lost energy when braking. Rolling resistance is tiny compared with air drag at highway speeds. Braking losses due to increased weight are only important if you are using the brakes, which rarely happens on the highway. On most highways air drag is by far the dominant factor in the fuel economy equation. Fuel consumption rate in gallons/hr due to air drag goes up with the cube of your airspeed. That is basic physics.
Stop and go traffic is an entirely different story.
