       Printer Image
The saying bigger is better is thrown around a lot these days, but the men and women who haul goods from coast to coast live that saying every day. With nearly 11 billion tons of freight amounting to approximately $16 trillion moving across the US annually, the trucking industry is the backbone of the US economy. Major truck manufacturers such as Freightliner and Peterbilt supply the building blocks in the form of durable and reliable trucks that create the foundation of the US infrastructure. Owners and operators are constantly looking for ways to improve their monetary returns on shipments any way possible. With fuel prices constantly increasing and regulations cutting into profits, finding ways to make a profit are becoming scarce.
