Just got back from our trip to the Pigeon Forge area. Truck averaged about 19 mpg for the trip, and that includes a lot of bad traffic in Smokey Mountains Park. Hand calculated differed but the computer any where from 0.4 to 1 mpg worse. One problem, the truck does not have nav. For 2017 they have whats called Sync 3. It has the large center touch screen and it lets you hook your phone up and use the apps on your phone, such as nav and pandora. It usually works great but sometimes the phone wouldnt hook up. I suspect the phone is the problem since turning it off and on would allow it to hook up. Its an iPhone 7. There are some complaints about it on the F150 forums. The phone Nav works great and even tones down the radio volume for turn but turn instructions. It also seems if you lose data connection on your phone, it keeps working as long as you have your destination keyed in before you lose data. We have unlimited data plan so thats not an issue. One complaint, the headlights. We rented a cabin away from town. Lots of winding roads. The lights just dont shine a wide enough pattern. When turning sharp corners you were doing so almost blind. I read a safety review and the truck did well on crash tests but got poor marks for headlights because of not a wide enough beam. A lot of vehicles got poor marks for head lights. Its really hard to say unless I drove a different vehicle on the same roads, since on normal roads, the lights seen fine.
