Shifting top halves?

I have a problem where my reefer vents get bent or torn when I open up the TM.

At first I thought something was caught against the vents, but now I suspect the top halves have shifted.  

The gap on the street side is different than the gap on the curb side (curb side wider).  Apparently the back half seals drag across the vents and mangle them terribley.  I've already replace the louvers once...

So I'm wondering if I should try to shift the top back towards the center...

Any thoughts or insights?
