Keep tire size and load rating, ground clearance and suspension layout, and spare tire, underbody protection and accessories in one versioned record for gravel-road adaptation, so all parties work from the same document. For gravel-road sourcing, check tire load rating, spare tire, ground clearance, suspension and underbody protection, then confirm that locally worn-out parts can be restocked. Before handover, confirm that tire size and load rating are logged and ground clearance and suspension layout is backed by documentation; re-confirm with both parties when spare tire, underbody protection and accessories changes. On completion, the person responsible for gravel-road vehicle sourcing signs off, records the dates of the documents used, and notes any exceptions that must be cleared before the next step.
