Kenworth says the new 40-in. sleeper for its T880 is designed for vocational applications that use straight trucks, such as petroleum haulers or the towing industry, and for tractors hauling flatbeds, lowboys or other trailers where length and weight may come into play. 

The 40-in. sleeper, which saves 260 lb over Kenworth’s 52-in model, features a 24-in. liftable bunk that tilts 90 degrees for easy access to under-bunk storage. There’s more than 22 cu ft of storage space to handle gear for occasional stays in the sleeper, plus storage shelves and a cell phone cubby. The interior also includes coat hooks specifically designed to hold hardhats as well as coats. There are three optional windows available on the back of the sleeper to help provide maximum outward vision for drivers operating in tight locations, plus two standard toolbox doors.

To help cover body builder equipment for all vocational applications, the  sleeper was designed with a height – from the bottom of the frame rails to the sleeper rooftop – that’s nearly 17 in. shorter than the T880’s 52- and 76-in. mid-roof models.

The T880 now offers vocational customers three sleepers.

On the T680 Kenworth has integrated battery monitoring with engine auto start and stop capability in a new option available on sleeper trucks, with or without the company’s Idle Management System.

Engine auto start monitors the starting batteries. It also monitors auxiliary batteries used with the battery-based Kenworth Idle Management System, or batteries used to power hotel loads through an inverter.  When batteries get to a critical level, the T680 automatically turns on the engine to begin battery charging.

KW says the system takes the guesswork out of battery monitoring, and it’s proactive: instead of shutting down battery draws, it automatically starts the main engine to keep all systems going while recharging the batteries to a steady state. Once at a designated level of charge, the engine shuts down.
