You'll do a walk-around, check key items, and record with forms and photos for maintenance and to show you did it right.
Designing a step‑by‑step walk‑aroundUsing printed or digital checklist formsTaking photos of key inspection pointsRecording defects and corrective actionsStoring records for audits and resaleLesson 11Simple load-rating calculation examples: tongue weight percentage, gross trailer weight vs tow vehicle capacityThis part gives easy load calculations for towing. You'll work out tongue weight percentage, compare trailer weight to tow limits, using real examples to stay under safe levels.
