The 2003 Mazda B2300 Reg. Cab 2WD Ext. Cab is published in 5 configurations, with tow ratings ranging from 1,420 to 3,900 lb depending on cab, bed, drivetrain, and hitch class. The peak figure (3,900 lb) sits in compact SUV / minivan territory.
The table below lists every trim of the 2003 Mazda B2300 Reg. Cab 2WD Ext. Cab 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.
