I think possibly I set the cams up where forward rotation was opening them if that makes since.I may be the odd one out, but we run a lot of chains at work on pickups, trucks and telehandlers. Quality brand square link camlocks have seemed to be the best. Throw away the camlock tool they give you and fab a good sturdy long handled tool to get some purchase and get things tight. I keep a compact floor jack in the truck toolbox and will jack each corner up and get them bitch tight if shits going to get real. always zip tie the tails back to a link against the sidewalls. I only run snubbers if I can't jack each corner up.
Sagebrush hitting the cam.
Where if I had swapped sides the cam would be forced further closed if it hit something.
Just a guess.
I need to ask my logging buddies but I don't think they run cams.
