venting

Excuse my crude plumbing drawing;

Can someone please recommend vent size and location.Wet or dry?

I am running 3" waste line from the new bath (on the left) to the existing bathroom. The vanity, shower and toilet branch off with T's. The 3" exits straight out to the septic.

The run is about 28 feet. I will slope it obviously 1/8 to 1/4 per foot.

Thanks for your comments an input.
