The Chevrolet Bruin (and similar GMC Brigadier) were heavy-duty trucks made by General Motors between 1978 and 1988. The Bruin & Brigadier were both conventional rigs using the 9500 series cab introduced in 1966; this cab was better-finished and more stylized than a typical big-rig cab but larger than the pickup-based cab used on the contemporary C40-C65 series. Diesel engine choices included Caterpillar, Cummins and Detroit Diesel powerplants.
