Ebbs, I did not install it , they did it . It is smooth all around no edges except the inside track. It is not overly heavy either.
No flap on the Highway at 80 mph . the frame is flull floating , clamps to inside under rail. they included a watertight seal under the rail to the caps.

 

Yes, this is is definitly a
good cover. I have had mine for almost three years and it still fits and works as good as new. I put that cover to the high speed test several times (130+) with no problems whatsoever.

You should not be disapointed
