Fuel Tank size?
That probably won't help you much. You need to fill it up until the pump clicks off. record the mileage, drive it until it's time to refill. Fill the tank until the pump clicks off again. Then divide the miles traveled, by the gallons used. This will be the most accurate MPG reading. Say you went 200 miles and used 10 gallons. That would be 200/10=20mpg
If you go to the specs at the top of the main forum page, you can look up all of the specs on your truck.
