Thanks for the info Ironman. What bracket did you add to it? The one that clamps the frame of the cover to the bedside? Other than the annoyance of it coming open, did you have any other problems? The plan is to secure everything into the bed by strapping it down, so the only forces on the Leer cover should be the cover itself. I wonder if there is a way to sort of latch it down so it doesn't open on it's own if you catch air. I'm thinking something pretty simple (and possibly not even effective) like a suction cup with tie down point on it on the top of the back of the lid and run a rope or strap down to the rear tow hooks? Might be kind of cheesy, but it might also prevent from having to stop all the time to close the dang cover!
I purchased another pair of frame/rail brackets and added it to the middle.
If you look on my bottom picture you will see 3 black flat looking things on each side. Yes it clamps it to the bed rail, this stopped my whole cover from vibrating itself off the truck.
With just the 2 on each side you would notice the cover hanging a couple inches off the back.
My cover bounces a lot because it has 4 scissor hinges that actually pick up the cover and move it away from the truck cab, it does
not have a solid hinge in the front.
These hinges allow this cover to bounce a bit too much while off road.
The one thing you could do is get a bungee cord and hook it on your trucks tie down hook. Short bungee to give tension.
Put one on both sides and hook them to the latching bar of the cover.
This will give your cover that extra pull down so it doesn't open.
Bellow you can see my broken cover hooks.
