If you’re thinking the 2007 International MXT would be a great ride to use for towing a fifth-wheel trailer, fuhgeddaboudit – that option is not offered, because the diesel V8 engine’s 300 horsepower and 530 lb.-ft. of torque can’t match the International RXT Tow Body model’s 310 hp and stunning 950 lb.-ft. of twist. Rather, think of the 2007 International MXT as the company’s “light-duty” sport truck, equipped with 4WD, an Allison 2200 RDS five-speed automatic transmission, hydraulic brakes with ABS, and a 40-gallon fuel tank. International says, by the way, that the MXT’s diesel engine should deliver between 13 and 15 mpg – about what you get in a Hummer H2 SUT.
