Start with route and payload
Clarify whether the truck will run on paved roads, mixed roads, quarry tracks or mine haul roads. Confirm payload using the vehicle documents and local rules rather than relying on a sales description. Compare 6×4 and 8×4 only after defining gradients, turning space, distance, material density and loading equipment. Body volume is not the same thing as legal payload.
Inspect structure and lifting equipment
Ask for close, dated images of chassis rails, cross-members, suspension mounts, body hinges and subframe. Look for cracks, non-standard welds, deformation, corrosion and evidence of previous repairs. With a qualified inspector, review the hoist cylinder, hydraulic lines, pump, PTO, controls, body movement and safety props. Record what was tested and what could not be tested.
Include roadworthiness checks
A pre-purchase review should cover service and parking brakes, tires and wheels, steering, lights, horn, warning systems and any coupling equipment. U.S. OSHA and Mine Safety and Health Administration checklists identify these as practical inspection areas; they are reference material, not a substitute for the destination country's legal inspection standard.
Record a test plan before the inspection
Agree in advance which checks will be static, which require a running engine and which require the body to cycle. Ask the inspector to record the truck identity in each photo set, note operating temperature and test conditions, and mark unsafe or unavailable tests as not performed. This prevents a short idle video from being mistaken for proof of loaded performance.
