Tonneau cover with Bed Rails?

Anything to consider when looking for tonneau covers if I already have bed rails?

 

Almost all brands will ask if you have bed rails when ordering.
Mine came with extra brackets and sliders that went into rail to hold brackets for my Gator cover.
Was a few extra steps.
Edit...
That's the inner slide cargo rails that is. Just noticed those silver rails on your truck. My particular cover wouldn't work, but there are some I've seen that would fit more inside the bed.

 

I installed the argi cover Lomax with the bed rails already installed from factory
after researching the covers on this forum & getting their takes on the covers
Its all about what functionality you want with a cover

I think this is a great cover no leaks maybe a tiny leak after a car wash & it looks great . It is a bit more expensive but well worth the price approx $150.00 more than the gator brand also great customer service & packaged nicely when shipped
Good luck with your purchase
