2015 Ford F-150 3.5L EcoBoost
We got this 2015 Ford F-150 with the 3.5L EcoBoost and 3.55 geared rearend last summer to pull our 2015 Jayco Whitehawk 24RDB. So far I am very happy with the truck because it pulls like a diesel, you don't even know the camper is back there. Pulling the trailer I have gotten as low as 10.2MPG fighting a headwind and as high as 13.3MPG. That is running the interstate at 65MPH.
Around town I get between 18.8 and 19.5 MPG. On the highway I get 20 to 21.5MPG. I actually got 23.5MPG one day going to my parents on two lane roads driving 60MPH. I was really happy with that. But I would say the 20 to 21MPG is more accurate on the highway.
