The Truck-Lite Second-Generation Road Ready System focuses on the master control unit (MCU). With a military-grade solar panel and a quick-charging battery, the MCU continually monitors crucial data from customizable wireless Road Ready sensors and transmits it to an intuitive user interface. Now, the MCU is available in either solar-powered or hardwired versions. The solar-powered MCU mounts on the front of a trailer, with the solar panel on top. The hardwired version allows the MCU to be wired directly to blue line power through the trailer’s nosebox, which charges the battery with power from the tractor. Each version communicates with Road Ready’s wireless sensor network and features the same long-life battery, which allows for untethered trailer monitoring for up to 60 days without a charge.
