Does 2018 GD Imagine 3170bh have AAV under kitchen sink?? Awful sewer smell!

[Laceycamille212]

We have a horrible sewage smell that seems to be coming from under the kitchen sink and possibly the shower. We found and replaced the AAV under the bathroom sink but cannot find one under the kitchen sink. Does anyone know if this model has an AAV under the kitchen sink? And if so do you happen to have any pics? If it doesn't have an AAV valve would replacing the roof vents improve smell? Thanks in advance for any help!! Attaching pics of under our kitchen sink and the roof vents.

We also had a sewer smell in our rig and at the time I wasn't aware that there was an AAV. I added a siphon roof vent like this. Haven't had the sewer smell since we added it.
