Hello, I am doing a full remodel of my bathroom (down to the studs) and will be replacing the existing single-sink vanity with a double vanity. I am proposing to pipe the drain as shown in the attached image but I am not sure about how to properly vent it. I've been searching for similar examples online but they all seem to be slightly different so I am not sure how to do it and that's why I'm here!

As shown in the image, can I get away with only one AAV by the sink farthest from the main line or will I need an AAV for each sink? Or is that completely wrong and I should do something different all together?

Thanks,
John
