Towing is configuration-specific
Chevrolet’s 36,000-pound diesel and 19,080-pound gas figures are maxima. The 2500HD maximum Crew Cab figure and every individual truck rating depend on cab, bed, axle, drivetrain, hitch and single- or dual-rear-wheel setup. Read the VIN labels.

- Request an itemized document for price, equipment or completed service.
- Check official recall resources and retain the result for the vehicle record.
- Recheck time-sensitive availability, incentives and ordering restrictions before committing.

Bottom line
Choose 2500HD or 3500HD from the load and hitch requirement, then select engine and trim. The headline maximum is useful for orientation but never replaces the exact payload and trailering labels.
