I left the passenger-side forward and moved the driver-side back, so I could look at it out the side window.
If you do the same, you will want to make a reflection/glare shield. mounts to the driver-side a-pillar, and prevents the reflection from the passenger-side front window. You'll see why it's needed 30 seconds after you swing the driver-side mirror back.
