Expert Insight: The Cost of an Unreliable 4×4
We once had a customer, a contractor, whose Silverado 2500 TCCM failed right before a big job. A surprise rainstorm turned his job site into a mud pit. Without his 4WD, he couldn’t get his equipment trailer into position, causing a full day’s delay and costing him money.
