80% hwy 20% city. Platinum reserve with 600 miles now. I got 21.4 mpg according to the computer. Speeds varied from 55-75 mph. Really enjoyed driving the truck. If the mileage improves from here I will be pleased. The mirrors that come with the truck work nice even if the don't extend out without being done manually. The led headlamps light the road very well. I think people need to give this truck more of a chance unless they really need that 3/4. Truck feels over built like it can do more than the stated capacities.
