Has anyone installed the Roll N Lock M series to their new 2015 truck...or could anyone maybe help me with this question?

I am looking at retractable covers and the Roll N Lock was highly recommended by a friend. However, I am not wanting to have to drill holes into my tailgate for the extrusion piece. I understand that there is a conversion kit where this may not be necessary, but has anyone had any experience with this? Does this increase chances for leaking?

 

I had the Roll & Lock installed on my '14 Platinum and am very happy with it's functionality.

Two small openings are required on the tail gate for the two metal hook/pins to lock onto the tailgate. The two small openings were then painted with Rust-oleum and a small brush.

This provides added security and the tail gate cannot be opened without the sliding cover being opened if left unlocked
However this type of cover is a bit pricey compared to others and I'm very happy with mine.
