I understand that water is channeled to the front of the truck, where water is expelled through 2 drain h oses. Does water run towards the back of the truck and get into the bed?
Absolutely not! Water runs along the inner track which acts as a “rain gutter” as well. This track is open ended at the back. This means that if the truck is parked up hill, water is collected in the inner track and drains right at the back edge of the tailgate and runs out of the back of the truck, leaving your cargo area dry. Water ever getting to this “channeled gutter is really rare under any circumstance!
