DAN--Not sure what other details I can provide.
Tommy, something like this:
1. How long have you owned the RV as you say it has been dumped 'twice'. Is that since you have owned it?
2. Is is a new RV and you have only dumped twice?
3. Have you been in one place for a while?
4. Have you been keeping the dump valve open while parked?
5. Have you checked anything, like maybe the vent tube?
6. Is the fan on in the bathroom?
Those kind of things may help people assist you with diagnosis.
Just trying to help....
