1999 GMC Yukon payload capacity
Payload is not the same as towing capacity. Where both GVWR and curb weight exist in the catalog, payload is GVWR minus curb weight (or the manufacturer payload field when present). Payload covers people, cargo in the truck, hitch equipment, and trailer tongue weight — not the full trailer weight.
- Observed payload range: 1,423 – 1,629 lbs
- Configurations with payload data: 4
Highest-payload configurations
- SLE 4dr · 4x2 — 1,629 lbs
- SLT 4dr · 4x2 — 1,629 lbs
- SLE 4dr · 4x4 — 1,423 lbs
- SLT 4dr · 4x4 — 1,423 lbs

* 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.
