Accurate Payload and Towing Limit Calculation

Cost Savings

Checklist Tasks

• Find GVWR and GCWR on the driver’s door jamb to set vehicle weight limits.
• Subtract curb weight from GVWR to find max payload, including passengers and cargo.
• Weigh loaded vehicle at a certified scale to confirm payload is within limits.
• Measure trailer tongue weight with a scale; keep it 10–15% of trailer’s total weight.
• Calculate total trailer weight, including gear and modifications.
• Verify rear axle weight rating supports loaded axle weight.
• Check tire load ratings match or exceed actual axle loads.
• Review hitch and receiver ratings; ensure they exceed loaded trailer weight.
• Include weight of aftermarket accessories that affect payload/towing margin.
• Add fuel, water, and propane tank weights for both vehicle and trailer.
• Check trailer brake requirements based on total weight and local laws.
• Record all weights and ratings on one sheet to avoid mistakes.
