Final answer:
To ensure the towing vehicle is within the payload maximum rating, you must consider the weight of the driver, passengers, cargo, and trailer tongue.
Step-by-step explanation:
In order to ensure that the towing vehicle is within the payload maximum rating, you need to consider the weight of various components:
- The weight of the driver only: This includes the weight of the person operating the vehicle.
- The weight of all passengers: If there are any passengers in the vehicle, their combined weight needs to be taken into account.
- The weight of all cargo in the vehicle: This includes any items being transported in the towing vehicle.
- The weight of the trailer tongue and its cargo: The weight of the trailer and its contents, specifically the tongue, which is the part that attaches to the towing vehicle.
By calculating the sum of these weights and adding it to the towing vehicle cargo weight, you can ensure that it is within the payload maximum rating.
