Sorry for the dumb question but - I have the bedliner and Re-Trax installed on my turck and I do not know where the drain holes are. Insted of taking evrything apart can someone lead me down the right path of where they are?

 

I would assume they are formed into the front of the ribs right behind the cab like the other styles.

There are no actual "holes" per se. There's just a gap under the ribs.
