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.
1. IF prepped for a washer Dryer, odds are the P trap has NO water and that is the source.
2. Air admittance valves Install a plastic baggy over them and test, OR just replace they do not cost much
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.
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
PS, IF a Black tank odor, the Flange rubber seal may be worn and bad.
