We have about 1,700 miles on our’s. Being that it’s not a daily driver, we don’t drive it much. Today we took a 189 mile ride, round trip. When we got back we topped off the tank. We drove 65 miles an hour on 95 in fla. we logged 16.3. The 1,700 miles and change says 14.3. That’s for all our driving including a 250 trip pulling a 6600 lb trailer.I believe we can get 12 to 13 towing and 17 to 18 on the highway. Hope you like your truck as much as we love ours. We just got a Retrax tonneau and skyline racks.
