Everybody assumes it is Black odor. Maybe, but after 44 years as a RV tech, most of the time it is Gray tank odor. Most people(SMART people) use a Black tank Deodorizer and break down chemical. Very few use a Gray tank chemical. What I do is dump and flush BOTH tanks. Then I install Pine Sol(about a quart) in the GRAY tank and then drive the RV. IF you get Pine sol odor, then you have a Gray tank problem.
I'll try that if nothing else seams to work, only because I can replace a seal while its in my driveway but I need to load the camper to do the test.. I have to wait for my 5th wheel to be fixed and brought home before I can load the camper... I need a dedicated camper truck I think haha.

2. Air admittance valves Install a plastic baggy over them and test, OR just replace they do not cost much
same thing, didn't use air atmittance valves on these, runs to short to need them, I was actualy hopingit was somthing that simple when I went hunting for them yesterday.

3. The down pipe for both the black and gray may not be sealed or installed to the top of the tank. To check fill both tanks to over full. Water coming up into the toilet bowl and water coming up into the shower pan, IF you get water flowing out off the top of the tanks, that is your leak.
I hope its not at the top of the tank as I think I would have to dissasemble 1/2 the camer to be able to reseal them. but the outside tanks and the vents are solid.
We did have a coupe times where there was water on the floor of the wet bath but there was aboslutly no stink or dirty looking water asociated with it so I figured it was a temporary leak even from the supply to the toilet, which I want to look at anyways.

4. The roof top tank vents, make SURE the 1.5 inch ABS pipe extends ABOVE the roof line and the pipe is sealed where it comes thru the roof. VERY COMMON
I did re-seal around them last summer and bought new caps thinking that would help.

PS, IF a Black tank odor, the Flange rubber seal may be worn and bad.
this is what I am going to do in the next coupke weeks. starting to get warm enough to work on things and since it is a 1991 camper (even though it looked brand new) it could have a bad seal
