What can I store and how does it organize gear?

In some models you may need to trim a factory floor liner or remove an existing underseat tray; the product ships with guidance and FengYu customer support is available for questions.

• No drilling required; installs in minutes in compatible trucks.
• May need slight trimming of factory floor mat in some trims.
