This stinky problem is not easy to completely resolve. Sewer gas and propane are the leading candidates under the stove. I my case it was sewer gas coming back through the vacuum breaker. I was able to isolate this by noting that the problem only occurred when the gray tank valve was open and connected to the campground sewer and it was worse with the Pod ceiling vent fan running. If it had been leaking propane it would have been present without a sewer connection and even at home in the driveway.

The function of the vacuum breaker is to allow air to enter the drain pipe downstream of the the P trap when water flow ceases, thereby preventing water from being siphoned out of the P trap. It's a one way air flow device: air into the piping but no air or gases back from the tank or sewer. There is no way to test while installed and probably not reliably even when removed. It must be vertical to work and works on very small pressure differentials. Best to replace if it's suspect. They're not expensive and are easy to replace.

All that said, the possibility of a propane leak also exists as a previous poster described. That is serious and dangerous and should be checked out.

Under the stove top there is a small valve. If you turn on the propane (for an hour or so) give this valve a sniff and see if it smells like "black tank smell." That is what was causing my smell.

I checked the vent. All I could figure out was that if I shook it, it should rattle a bit. Is there any other way to determine if it works properly? I understand the principle behind how it works, but not sure how to troubleshoot one.

Seems like lots of things can stink in a small space. Can't always blame the dog ;)

I had a similar stink problem when connected to the campground sewer and the gray drain valve open. Particularly bad wiht Fantastic fan running. It was the vacuum breaker vent under the kitchen sink/stove.

Even without warranty, it's not that expensive. Not a $500 fix, should be safely under $100 even with labor.

I will definitely check that one out. That's where I was thinking but I didn't know about that part. Warranty just expired a few days ago, but if that'll fix it, I'll pay.

Thanks for checking the posts.

It's the small propane regulator valve under your stove top. Pop the stove top off, give the valve a good sniff check. I'd bet that is it because mine did the same thing, I thought it was "tank smell" but it was propane. My dealer replaced the defective valve under the stove under warrenty.

Thanks for the suggestions.
The smell came on the day three of our stay. We hadn't been pulling or even moving. Sink had been used regularly for dishwashing, etc. Smell seemed strongest under the stove (inside the drawers). Traps were filled in shower and sink. Maybe  the kitchen sink siphoned out the trap? But the utility vent should have prevented that. True that lots of things smell rotten. I've learned that one the hard way before.

BTW, stagnant grey water can smell somewhat like ethyl mercaptan (propane is odourless - ethyl mercaptan is added specifically to give it a recognisable odour).

1st, welcome to the forums and podding. Wink

You can get a "smell" if the "p" traps dry out or splash out while pulling, or between uses, and then it magically goes away as soon as you do something that refills them.

Sometimes you can have the bad luck of being oriented in a way that causes the vent pipe odor to find it's way back in also.

To address your other issues.. more or less..

1) the brakes are electric, the wires can get damaged.. one of the things to check.
2) totally "normal" to find the valves in the winterization position on a new pod, we see it on here weekly.
3)Have to admit.. that is a new one, any stove that wouldn't light previously just needed purging.
4)again, something to check every now and again.. The trailer uses pretty much the same types of plumbing connectors as your home, you never have to worry about those because your house doesn't move around as much.. except maybe in California.. LOL.
5) Some people have removed the dividers, I have never heard of them breaking. But again, stuff moves and shifts while in transit, and, the Pod is built to be light, so some materials are not "tank like".. All we store down there is bread/crackers/marshmallows/cookies.
