'16 Crew cab 3.5 Eco Boost (3.55) with 63K on it. Love it. it is in no way light in the rear end and I travel plenty of snowy roads. I travel the freeway a fair bit and get 21-23 consistently unless it is winter or hit a big headwind. Overall, like others, in the 19 range unless pulling. Speaking of pulling, I just pulled a 8.5 by 16 enclosed trailer that catches a fair amount of wind to the mountains on vacation. I could go as fast as i wanted. The mileage suffered just like they all suffer but the impressive part was that I had plenty of power in the hills and mountains.
