Well, that'd be an option with the plastic Lund brackets then too Terry. Use two or three to mount one track on and then slide and lock all three down. But again, even loading a few rods in holders off of that, I'd still be leary in the end.
I just drilled for Scottys as the mounts are small and stay under the cover.
You'll like this one of Andy flippin me off. lol. And, you can see what the brackets are actually getting used for. lol.
