Completely different. The assessment of commercial vehicles focuses on: the extent of wear/deformation in the cargo area, whether the frame has been twisted due to overload, the fatigue of the leaf springs, and the emissions of the diesel engine.

Experience turbo lag and power surge during road tests; check for significant oil accumulation at the turbo intake and intercooler connections (slight oil vapor is normal); and use OBD to read the real-time boost pressure peak to see if it meets factory settings.

It's not mandatory. Four-wheel alignment and dynamic balance are part of routine maintenance. During long-distance towing and sea transport, the suspension may experience slight changes in stress. We recommend that buyers perform a four-wheel alignment locally after picking up the vehicle at the destination port and replacing tires suitable for local road conditions.
