Rear window sizes are different.

I just noticed this today when cleaning the Tahoe. From the outside, they're the same, but the actual visibility or the "window" from the interior to the outside is smaller on the passenger side than of the driver side. I wonder why this is? It could be why the 3rd row seat rubs on one side and not the other.

I noticed that too, its like that on almost all suv's.
One rear quarter window is always smaller on the interior than the other!

There is a HVAC duct on that side that feeds the ductwork in the ceiling.
