Well, as you can see from the pictures of our 29 mvp the window is only slightly off center.
Looking at the inside picture will give you a clue as to why it is off center. Look through the window towards the front from the outside picture. Notice you can see through to the front windshield.
With the slide out in for travel you can still see out the window as the slide does not cover any of it. Also, it can be viewed from the drivers seat with the rear view mirror looking back I can see the top of my Jeep behind us plus any tailgating drivers.
