Question: 

How do I know which Tow & Stow adjustable drop hitch I should purchase?

Answer: 

For most vehicles, the 3" drop is the appropriate Tow & Stow hitch. However, if you have a pickup truck with oversized tires, a lift kit, or a trailer that is not at the same relative height as your receiver, you may need a 5", 7", or 9" drop hitch. The following diagram depicts how to calculate what is commonly referred to as 'drop.'
