Newby Question-Screw holes in bed rail under back sliding window?

I've noticed there are 2 screw holes directly underneath the back sliding window-they are right in the middle of the back bedrail. Does anyone know what these are for as I have no idea?? Makes me wonder if something is missing there? Thanks for your time!!

 

Those are for the factory Tonneau Cover!

 

Thanks-now I know. I'm looking at roll up Tonneau covers now. Can you mount one without cutting holes in the bed liner and does the rail system in there get in the way?? I want a low profile cover something like the Rugged Line or Truxedo Low Pro, but if holes have to be cut-not gonna do it??? Thanks everyone-again this is a great place to learn!!

 

I love my Bakflip F1. Super Lower Profile and folds all the way up so you can access 95% of the bed instead of loosing 1/3rd of the bed space!!! And also with the new system you get to keep your rail system they just give you relocation brackets to lower it about 2 inches!

 

^^^ Overloaded... reported...

 

Anyone done anything cool with those holes if they don't have the factory tonneau cover? Maybe some eye bolts for extra tie downs??

 

Nope. I put a bakflip F1 on my truck!

 

reported as well.

 

Do like that the last section folds right up against the cab for maximum bed usage but i still prefer the look of the factory cover...one bolt and off it comes, 100% of the bed use
