It's about $6k more. Better mileage and just being better make it worth it, easily. Still, being a cheapass, I'll buy an unsold previous year model for less than an F150 work truck with the tiny Ecoboost. The dealership still had 4 2017s left and one was an Ecodiesel in Gator blue with a saddle leather interior. So, Imma' get it tomorrow. We're haggling around $39k while the sticker is $54k. Still, I walked away today trying to get them to throw in one of those built in winch bumpers. Like this but color matched to the truck.
