Peterbilt has introduced a 58-inch sleeper for its Model 579 in both low- and mid-roof configurations for weight conscious short- and regional-haul operations. The new sleeper will go into production in the fourth quarter of 2015.
The 58-inch sleeper reduces weight by up to 100 pounds compared with the 80-inch sleeper while still including the same amenities found on the larger sleepers. The sleeper includes a full-length door for loading personal gear and belongings into the truck. It also has full-length integrated extenders to minimize trailer gap and improve aerodynamic efficiency.

Other features include a television mount, refrigerator and microwave shelf. Peterbilt is offering the 58-inch sleeper Model 579 on both low- and mid-roof configurations to increase its versatility to meet specific application requirements, including flatbed and tanker operations.
“The sleeper was designed with extensive research and customer interviews to help ensure every inch of space was considered for a layout that was both practical and premium,” said Scott Newhouse, Peterbilt chief engineer. “Operators will enjoy the full-length mattress and abundant storage areas, including the cabinets, under bunk and back wall.”
The companies also said they plan to coordinate deployment planning across priority freight corridors and define routes and operational design domains for U.S. commercial service while laying the groundwork for expansion into key European markets.
