When is too much, just plain too much? When International, a maker of heavy-duty trucks, decides that what the world needs right now more than anything is a monster SUV that weighs 7 tons, twice as much as a Hummer H2. The new CXT (for Commercial Extreme Truck) stands 9 feet tall and is more than 21 feet long – more than 4 feet longer than the Hummer H2 pickup. The CXT is a development off of the heavy-duty platform that International uses for its rugged-use trucks designed for road work and snow plowing, etc., and gets between six and 10 miles per gallon (we’d venture closer to six) from its commercial truck diesel engine.
