The proper gearing for a gasoline powered tow vehicle is more difficult. To take full advantage of the trucks power band you might want a 5.36 gear ratio behind a 6.2 engine. The trade off is that when cruising empty down the highway in overdrive at 75 mph the engine will be running at close to 2700 rpm and using more fuel than it would if you had a 3.55 ratio. Usually if someone is buying a gasoline powered truck they have in mind that they won't be pulling most of the time.
