Smells from kitchen Thor hurrican

[GDTRFF]

I’m getting smells from below the sink on start up after retracting the slide. There are. I leaks from the sink, everything is dry underneath and the smell does not seem to be coming from the drains.
Is there a file hose beneath the floor?
Where could it be coming from?

Replace the Air Admittance Valve (AAV) with a quality one from the big box store of your choice.

Had same issue. A cap under the sink on top of an exposed drain line fell off. Needed a flashlight ti find it done below behind bottom of sink.
Pulled it out and threaded it back on and all smells are gone.

We also use Walmart white venigar in the kitchen and bath sinks once every 3 months. We let it sit in the p traps for a couple hours.

Also...the sink drain hose to the gray tank under the slide is notorious for cracking off the top of the tank just enough for odors to flush out as water goes in. I had this issue and it's a real bear/arm bleeding affair to repair it. Dealer wanted 4 months wait and $1,200 to fix it. I did it for $26 with local parts from hardware store. Let me know if this is what you find and I'll share my solution, which included some flexibility. I'll never buy another coach with the kitchen in the slide...too much crappy construction for too many moving parts.
