We did tow our 27 foot Heartland Trail runner with an F150 with Ecoboost. It weighs around 8,000 pounds when loaded up. Plenty of torque and horsepower with that engine but where we ran short was with payload. With the tongue weight and the weight of me and my wife, we were out of payload. We were also getting close with axle weights so I traded that truck in and bought a 2015 Silverado 2500 HD with the 6.0 Liter V8 Gas engine. It won't win any speed races but it will tow anything that I will ever own and when towing, speed never enters the equation.
