I just pulled up a picture of an older 3023 off of Google and it had that AC right over the rear bed. I can only imagine what that is like, but I don't think i would like it there.

On our 2720, it is located at the rear of the front shell that pretty much centers it in the TM. Since our AC blows air toward both the front and rear at the same time the temperature remain fairly even front to rear.
