Actually, it's quite common to use gallons/ton-mile as a unit of fuel consumption in the trucking and freight industry. It allows you to tell how much fuel your using per ton of freight moved. If you were only concerned about how many miles/gallon you used, you could just haul less freight, so that's why they use gallons/ton-mile.
