2000 GMC Sonoma towing capacity
The 2000 GMC Sonoma is published in 14 configurations, with tow ratings ranging from 5,900 to 6,400 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (6,400 lb) sits in mid-size SUV / pickup territory.
The table below lists every trim of the 2000 GMC Sonoma with the engine, drivetrain, axle ratio, horsepower, torque, GVWR, curb weight, and payload that go with that trim's headline tow rating. Manufacturers often publish more than one tow figure per truck — a conventional bumper-hitch rating, a weight-distributing rating, and a gooseneck or fifth-wheel rating — so the highest number here is the maximum across all hitch classes the source carries for the trim.

How to interpret the headline tow figure
Tow ratings at this level are normally achievable with a conventional Class II or Class III receiver hitch. Always verify your vehicle has the manufacturer's tow package installed if you intend to tow at the upper end of the rating, and inspect the door-jamb sticker for the actual maximum permitted on your specific configuration.
How this year compares to 1999
The 1999 GMC Sonoma carried a maximum tow rating of 5,500 lb. The 2000 model adds 900 lb on top of that — usually a sign the manufacturer added a tow package option, refreshed the powertrain, or revised hitch class certification. See the 1999 GMC Sonoma page for the full per-trim breakdown of the prior year.
