Full disclosure: Ford guy here. But if you really want the best pulling 1/2 ton the ecoboost can't be beat by any gasser
It really is like an older diesel in its power curve. Tons of low end torque. Any 1/2 ton v8 will rev like crazy to pull any sort of weight. I've had chev 6.0, and several ford 5.4's even a dodge but it was small v8. Gas mileage is better than my last 5.4 but not super. If towing is what you want the ecoboost is hard to beat.
