Known issues on the 1983 Brigadier. Federally the truck is clean — no recall, and no owner has complained to NHTSA. That leaves the manual to be judged on coverage, which is broad. Every named engine on the list gets procedures, specifications, torque values, wiring diagrams and diagnostics, and the short conventional cab, frame, driveline, brake and electrical systems are documented alongside them, so one book serves a yard running several different diesels under the same hood line.
