The cargo area has the ability to operate in many different configurations (endgate, midgate and roof opened or closed), allowing the cargo and passenger area to be open to the environment. To allow the vehicle to operate in these configurations, it is equipped with features to help resist the elements and protect the cargo inside the cargo area. Parts of the water management system, which are designed to quickly direct water out of the cargo area, are the cargo floor mat, front and rear floor drains, wheelhouse drains, midgate drains, and the midgate sliding hinge panel.
To ensure that the water management system performs properly, ensure that all parts of the water management system are clean and not blocked with debris.
Important: All drain valves are removable for cleaning of the valve and the drain channel. Note the position of the drain valve to the vehicle before removal. Improper installation of a drain valve will allow improper draining of the water and possible excessive water intrusion into the cargo/cab area.

For the cargo area parts identification, refer to Cargo Area Water Management System Identification .The cargo area has floor drains located under the cargo mat near the sides of the cargo area.
The midgate drains are located under the midgate.
The wheelhouse drains are located on each side of the water management trough, under the midgate sliding hinge panel.
