I have little direct expertise with this generation but let's assume both have a factory Honda trailer hitch installed. They use the same part number with the same capacity. However, the 2000 has a 4 speed auto transmission where the 2003 has a first generation 5 speed auto transmission. The engines are similar but slightly different overall. I take that to mean the engine/transmission combination for 2003 may be more towing capable overall than the 2000.
