Leer XQ Cap Gaps

I just bought a new Leer XQ cap and was wondering if anyone else is having this issue. I thought the the cap would fit more snug along the sides of the cap with the truck bed. But for some reason I have about a 1/2" gap on one side. Is this normal or not.

 

I have an xq also and the only gap I notice is up in the front of the bed toward the cab. There's an opening there in the bed, appx 1/2" or so. Also I notice some gaps right near where the tailgate meets the side of the bed and where the cap window closes.

 

most caps ive seen dont fit like a glove,if that helps.

 

Mine is about the same.

 

My XQ was installed poorly, they left it hang off the back of the truck like 3/4" and it was not completly centered side to side with the bed rails. I think this was because they were to lazy to properly adjust the rear windows to seal with the taigate.
I loosened the 4 mounting bolts and adjusted it and the back window and it is much better now. If I was to do it again I would of bought the next model down with the conventional hinges for the back window instead of the XQ's hidden hinges.
