I had a 2012 F-150 Ecoboost w/ 3.72 gears. No issues towing my 5'er. I did upgrade the suspension and added Timbrens. Eventually, I realized I was asking this truck to do more than it was designed to do. I miss the F-150, but towing with a 2500 is a breeze. Besides, I want to start going thru the Smokies and go out west. The F-150 would be way out of its league on that terrain. Flat terrain mixed with caution, it can be done. People underestimate the power and torque of a Ecoboost. In the end, it is not all about the power and torque.
