Start with your loaded trailer and the people riding in the truck. GMC’s highest 2027 Sierra 1500 trailer rating is 13,500 pounds, but the highest number is useful only if the specific truck, hitch and load all qualify.
| Example configuration | Maximum trailer weight when properly equipped |
|---|---|
| 5.7L V8, Double Cab 4WD, Max Trailering | 13,500 lb |
| 5.7L V8, Crew Cab 4WD, Max Trailering | 13,300 lb |
| 3.0L Duramax, Crew Cab 4WD, Max Trailering | 12,100 lb |
| 6.6L gas V8, Crew Cab 4WD | 9,400 lb |
Do the payload calculation for your truck
Suppose the label on a truck gives it 1,800 lb of occupant-and-cargo capacity. If people weigh 600 lb together and the hitch hardware, tools and bed cargo add 300 lb, that leaves 900 lb for trailer tongue weight and anything else you put in the truck. A measured tongue weight of 1,000 lb would exceed that example payload even if the trailer is below the advertised tow maximum.
These are example weights, not a Sierra rating. Use the labels on the actual truck, the loaded trailer weight and tongue weight, hitch limits, axle ratings and gross combined rating. Do not combine maxima from different trucks.
When should you compare a 2500HD?
If the family, bed cargo and tongue weight exceed a 1500’s limits, a larger engine alone will not solve the problem. Compare the 2027 Sierra 2500HD using its own labels. Bring both sets of numbers to Circle so the comparison reflects your camping or work setup.
