1. Match identity across the truck and paperwork
Photograph the chassis or VIN marking and vehicle plate, then compare them with registration, export and refurbishment records. Record the exact series, model code, year and steering side. Resolve mismatched or unreadable identifiers with the seller before a deposit. NHTSA VIN resources illustrate why identity should be checked against manufacturer records; local procedures differ.
2. Record powertrain and emissions identifiers
Ask for engine make and model, power rating, gearbox code, axle layout and ratio, tire size and any emissions label. Check agreement with vehicle documents and intended work. Emissions labels and certification systems are jurisdiction-specific; EPA guidance, for example, uses heavy-duty engine-family information for U.S. checks. Confirm the destination's own import and registration rules.
3. Use catalogues for orientation, not proof of condition
A manufacturer catalogue helps identify model families and applications, but options change by production year and market. Ask the factory for a build sheet or written configuration list for the offered unit, then obtain a dated inspection, start-up video and road-test record. Confirm local parts availability for the exact engine, gearbox and axle identifiers.
Build a plate-to-document cross-check
Capture clear images of the chassis/VIN marking, vehicle plate, engine plate and relevant component tags. Compare model code, year, engine, transmission, axle and emissions details against the build sheet and offer. Keep a discrepancy log with the source of each value and obtain a written resolution before the contract specification is frozen.
