If the "Bob stink test" dont work mabye someone can be on the roof and listen for air being sucked into the correct air vent as you dump the black tank?

good idea...another variation might be to have someone run some water into it while listening
on mine it's obvious....toilet is on driver's side and all the grey water stuff is on the other side. Up on the roof i have one vent each side....
