I got a front runner roof rack that I had mounted by the pros 2 years ago and I only just realized that they mounted it not on the channel of my D40 but a bit further in towards the middle of the roof. About 20mm away from the channel that runs along the outside each of the roof of my D40.
I was lead to believe that the strongest point for mounting anything to the roof is the channel which is much thicker there than anywhere else. That channel is where you should be drilling holes to tap into.
Can someone please give me some insight. Am I at risk of failure if I take this roof off road and / or load it up?
What has brought this up was all the controversy lately of rhino racks being mounted on car roofs using rivets and failing. Mine has not been rivereted but screwed. ie. The rail is screwed into the roof and then the feet of the rack is installed on that. The feet hold up the rack.
