Good for roll-overs–not good if you are trying to penetrate it to install rails for a roof rack. To install the rail, I need to drill 9 holes for each rail–18 total. Six of them are above the cab area.
I began drilling Thursday after receiving the shipment. The first 6 were done in less than 15-minutes. I worked on the next 3 for about 5 hours–new drill [variable speed] included. No joy!!!
Today [Saturday], I drilled 6 holes for the nest rail and did not try the 3 above the cab. I called a rack installer. They are familiar with my plight; but, they cannot drill the 6 holes for me until Tuesday morning at 10:00 am.
