No matter where you drive, chances are good that you will see the mighty shape of a Peterbilt truck somewhere along the horizon, tirelessly churning through the miles to deliver food and other goods to stores throughout the land. Without Peterbilt sleepers, the consumer landscape would be a different and much less colorful place. Peterbilt sleepers allow truckers to remain fully self-sufficient, giving them the ability to get a decent night's rest no matter where they are. The sleeper has two compartments — a cab that offers incredible views of the highway, and a sleeper section with a bed and room to fit a 6-foot driver comfortably, at least in the UltraCab model. The Peterbilt UltraRide seats offer comfort and stability for the driver and any passengers, a necessary component of any long haul. Engine choices for new models include a PACCAR MX-13 and a Cummins ISX15, delivering the most advanced and efficient powertrain available. The Peterbilt 357 and 379 are two popular variations of the sleeper.
