Wabash National last month hiked prices on new trailers by 4.5 to 6 per cent. The LaFayette, Ind., manufacturer says increases are necessary to counter higher prices for raw materials like steel, aluminum, and wood. “The pricing environment for most of our trailer types over the past three years has remained stable or decreased as we have held or passed raw material-related savings onto customers,” says Bill Greubel, president and CEO. “The trucking industry has become very adept at managing their cost increases, including fuel, with their customers. Unfortunately, Wabash National is now facing similar circumstances.”
