The maximum gross trailer weight (trailer weight plus cargo weight) must NEVER exceed the weights published in your owner's guide. This weight varies across the Toyota truck product line. It varies from vehicle to vehicle and is also dependent on the engine size and whether the vehicle is equipped with 2WD or 4WD. Always follow the recommendation in your owner's guide or consult an authorized Toyota dealer.
The gross vehicle weight must NOT exceed the Gross Vehicle Weight Rating (GVWR) indicated on the truck's Certification Label, usually found on the driver's side door post. The gross vehicle weight is the sum of the weights of the unloaded vehicle, driver, passengers, luggage, hitch and trailer tongue loads. It also includes the weight of any special equipment installed on the vehicle.
The load on either the front or rear axle resulting from the distribution of the gross vehicle weight on both axles must NOT exceed the Gross Axle Weight Rating (GAWR) listed on the Certification Label.
