* Payload = manufacturer payload when present, otherwise GVWR − curb weight. Towing capacity is a separate rating and is not the same as payload.
What affects the rating
Higher figures usually need the tow package, the right axle ratio, and enough cooling. Passengers, fuel, gear, and tongue weight all eat into what you can safely pull — stay under both the trailer rating and the vehicle’s payload.
