I’ve had a 12,14,17,19 all 3.5 ecoboost and loved all of them. Took them each to 95,000 and traded. Had a few issues with the first one and heard the 11’s were trouble. I would look into the latest model as you can afford. They are unlike any other gas engine on the market. Tons of low end torque. Terrible mileage when working hard but so is everything I guess.
