From @IvanNik photos, i noticed that the panels mostly attach via the bedrail mounting points, but there seems to be some mounting hardware closer to the floor of the bed that my truck doesnt have (i.e., near the wheelwells and the D-ring tiedown anchors, etc.). I am installing a bedrug so want to make sure i cut out access to whatever i might need in advance, but im not clear where those lower mounting points are going to if no drilling is required? Can someone help clarify?No it doesn't
