I need help to eliminate a sewer smell coming from the sliding door area going upstairs in our fifth wheel. The door is on the opposite side of the toilet. There are no leaks. I have looks underneath in the storage area and still cannot find the source.

You may have a vent that is pulled up out of the tank.
If nothing else, use chemicals to stop the smell.

Looks again. A plugged vent is my guess.

Get a clear fitting. Dump, fill with some water, dump, fill, repeat until it runs clean. You will likely be amazed at how much "stuff" is left in the tank with just a simple dump. I have to fill/dump several times to get it all out. And before all the backseat campers ask, yes, I am using plenty of water to start with after a dump and during usage.

Check the vents are clear and the traps hold water.
What is in the tank should have no impact on what you smell inside.

Is there a tank vent near a roof vent?
Hit up a dollar store and buy some pinesol like ten bottles of it, as mentioned above, get a clear sewer line fitting and dump file rinse repeat until everything is out then dump a gallon or two of pinsol in and leave it for a while.
I do this a few times a season and try to drive with the cleaner in the tank. Downy scent Perls or what ever the are called are good to.
I dump about 10 bottles for the winter season.

I know you said you checked for leaks but it doesn't take much to get that smell.
Gray tanks need to be cleaned too or else they'll get the same smell

We had the same type of steel in the kitchen area caused by a faulty air admittance vent under the sink. Replaced it, smell was gone.
