Take your truck information and look online. Usually there are guides for the spec of certain vehicles. Someone should have the towing capacity listed.
You just have to plug the model of the truck and the words 'tow capacity' into a search engine. That should give you the answer you're looking for. If not, call the dealership.
You'll have to contact the manufacturer because each model has a different tow rating. Most diesel engines can tow more while gasoline engines tend to have higher horse power.
