Kenworth's Idle Management System comes factory-installed for its long-haul T680 with a 76" sleeper. It has a battery-based APU system for air conditioning that is tied directly into the Kenworth T680's ducting system. An optional fuel-fired heater provides full engine-off heating capability. It features full on-board controls in the sleeper, so once the truck is shut down, the driver simply uses the control panel in the sleeper to maintain temperature control. An LCD display gives drivers full system information, plus allows the driver to monitor remaining battery power.
