Been installing mine the last 2 days. After getting microwave on the floor there was 9 inches from the mount to outside wall. Had to make a wall to hold the new duct work . After cutting through the inside wall with a dremmel ,I found a aluminum stud. I decided to keep going on with project and made a 2 inch offset to miss the stud. Worked out good so I finished putting duct work aluminum tape to seal it up...Works good and its quiet.
