I have a 2015 5.0 4x4. No issues at all. Stomp on it and it will smoke the tires. I think I have 86000 miles on it so far and gas mileage average over the life of the truck is 18.2. Not bad for a lead foot. It will get 21 MPG going 70 with cruise control. It has 20 inch wheels and I think 3.31 rear end and 6 speed transmission. If I was going to tow a large percentage of the time I would look for one with the 3.55 or 3.73 rear end. Mine tows my pontoon boat well but needs to be in 5th gear most of the time unless the road is level then it cruises in 6th easily. It's been a great truck and would buy another in a heartbeat. The 302 has been around for many years.
