This 2024 Kenworth T680 is a high-efficiency Class 8 sleeper with just 417,131 miles on its Cummins ISX engine, offering a versatile build with a Gross Vehicle Weight Rating (GVWR) of 80,000 lbs and a lightweight chassis design for maximum payload capacity. Identified by VIN 1XKYD49X2RJ328627, this unit is configured as a 6x4 tractor with a 125-inch Bumper-to-Back-of-Cab (BBC) dimension, featuring a tandem rear axle (40k–46k lb capacity) and a 12k–14.6k lb front axle equipped with air disc brakes for superior stopping power. While it boasts Kenworth’s most advanced aerodynamics, a custom 15" digital dash, and integrated Bendix Wingman Fusion collision mitigation, potential buyers should note a moisture-sensitive electrical issue: during heavy rain, a gauge—likely oil pressure or coolant temperature—spikes to 130, causing the ECM to trigger a safety shutdown. This behavior, likely tied to a sensor seal or harness rub-through, presents an excellent opportunity to acquire a nearly-new, high-spec tractor with an addressable electrical quirk that can be isolated using the onboard diagnostic fault codes.
