To find the exact towing capacity for *your* specific 2006 Dodge Dakota V6, you should:
* Check the sticker on the driver's side doorjamb. This sticker will list the maximum towing capacity for your truck.
* Consult your owner's manual. The owner's manual will also provide detailed information about towing capacities and other relevant specifications.
Without knowing the precise engine and configuration of your Dakota, I cannot provide a reliable towing capacity figure.
