3.5 Ecoboost Feels Like a V6

So I have a 2017 F150 with 3.5 Ecoboost and 3.55 gears. I rented a 6x10 dual axle dump trailer and loaded it with 2.5 yards of landscape rock. I'm thinking maybe 8000-9000lbs total.

Engine did the job, but felt like a lawn mower. My previous 6.2 V8's easily outperform this motor. Now I know why this motor can't be placed in a Super Duty.Trailer also pushed the truck around and was tough on the brakes. Thankfully only went about 8 miles.

This motor is great for anything 5000lbs or less, as long as you are fairly aerodynamic. My truck gets 7 mpg towing an ultralight Passport 153ML.

Since I drive most miles empty, I like this truck and it is a good compromise. If I pulled over 5000lbs and used the truck only as a tow vehicle, I would pass.

Y I have towed 12k lbs with my ecoboost and it will run like a bat out of he%$.
Sounds like your real complaint is the fuel mileage while towing. Towing a 10k lb fiver I get about 7.5 to 8 mpg at 62 mph with my ecoboost. My 6.7 Powerstroke gets about 10-11 mpg at 62mph with the same fiver.
