Tonneau Shudder

[Quigs]

Yesterday was the first time I got to drive my truck with my new TonneauPro tri-fold on. It was pretty windy and I noticed at highway speeds that the whole truck would shudder because of the cover when I would get hit with a cross wind. Has this happened to anybody else? Everything feels like it's clamped down nice and tight, should I see if I can crank it down a little tighter?

I just got the same cover. I haven't noticed the truck shuddering, but I do see the cover flap a little at speed ( more like ripple, not actually flap). Mine is cranked down pretty tight. The front clamps almost all the way. It looks like the clamps are just grabbing the plastic bed caps, but there is a metal lip under that for the clamps to grab.

I've had that cover since november 2012 with no stink'n shudder.

Sounds like I might need to crank it down some more. Maybe the wind was getting underneath it.
