No lift and fuel mileage has been unimpressive since the repair. Most of the time I'm in single digits around town and towing. Still have a vibration at highway speeds which myself and passengers can feel, yet no one at Ford can ever recreate. (Even WITH my assistance!) Love the truck, but after two bad eggs, this will be the last one. I shouldn't have to fight with the stealership over fixing a $50,000 truck that's less than a year old.
