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
