Trailer Hitch Classes

There are five different classes of hitches for towing. Your trailer class size depends on what you want to tow and what vehicle you’re towing with. Read below to find out what hitch class is best for you!

 

Terms to Know


Gross Towing Weight (GTW):
The total amount of weight you will be pulling, including cargo.

  • How to find GTW: You can get this number by putting your fully loaded trailer on a scale.

 

Tongue Weight (TW): The downward force exerted on the ball by the trailer coupler.

  • How to find TW: Using a TW scale is the easiest way. You can also use a bathroom scale that you have at home if you have a small trailer. This video will guide you through how to set it up properly. However, for best practices we recommend the Sherline Trailer Tongue Weight Scale. It will scale up to 5,000 lbs, but they offer lesser weight options as well if you know you will only be towing smaller loads. 

You can find more towing and trailer terms on our Glossary page.
