How to identify this era
- Earlier T680 hood, bumper and fairing design
- Earlier dashboard and instrument arrangements depending on model year
- VIN, certification label and factory build sheet
What changed
This era established the T680 aerodynamic cab platform. Changes accumulated across model years, so it is best treated as an earlier-production research range rather than one fixed specification.
Powertrain context
Depending on model year and original order, buyers may encounter PACCAR MX or Cummins engine families with manual or automated transmissions. Confirm serial numbers, ratings, calibration and rear axle ratio.
Cab and sleeper
Day-cab and multiple sleeper configurations were offered. Confirm sleeper size, interior generation, HVAC, bunk and storage equipment on the actual truck.
Technology
Instrumentation and safety equipment evolved during the era. Do not assume a feature is present from the exterior appearance or model badge.
Emissions context
The range crosses multiple emissions and aftertreatment updates. Identify the engine and emissions generation and review repair and regeneration evidence.
Used-buyer verification checklist
- Factory build/specification sheet
- Engine model, serial, hours and idle hours
- Transmission model, clutch/actuator history and rear ratio
- Cab/sleeper, axle ratings, wheelbase and suspension
- Aftertreatment service and fault history
