Peterbilt’s lightweight 58-inch sleeper is now in production for the company’s flagship Model 579 and vocational Model 567.
The 58-inch sleeper is available in low- and mid-roof configurations. It includes a full-length door to help facilitate loading personal gear from outside the truck and includes full-length, integrated sleeper extenders to minimize the trailer gap and improve aerodynamic efficiency.
Peterbilt says the new sleeper can reduce weight by up to 100 pounds.
“Peterbilt’s 58-inch sleeper is ideal for short- and regional-haul operations where less weight and a shorter wheelbase are critical,” said Robert Woodall, Peterbilt assistant general manager of sales and marketing. “It includes all of the amenities found in Peterbilt’s larger sleepers, including ample storage, driver comforts and exceptional fit and finish for quality rest and off-duty time.”
With research and customer input, the sleeper was designed to make use of every inch of space so that the layout would be practical and comfortable for drivers. By offering it in low- and mid-roof configurations allows it to meet specific application requirements such as flatbed and tanker operations.
“The new 58-inch sleeper is designed with an open, spacious feel that drivers expect from a Peterbilt sleeper,” said Scott Newhouse, Peterbilt chief engineer. “It’s thoughtfully engineered.”
