What size are the tires on the truck? If you have really tall tires a little more gear.Decide how much high way driving you will be using the truck for and the RPM that you can cruise at with out going crazy. 3.73 is a good place to start your calculations. 62 mph =2700 RPM with 29 inch tall tires,,,62 MPH=3200 RPM with 25 inch tall tires
