IF you can smell waste tank odors inside your RV then something is wrong/broken.
Mechanical seals and vapor barriers prevent odors from coming inside.
Toilet.....fill bowl to flush #2
Dump black tank when at least 3/4 level to full. High liquid to solid ratio works best at evacuating tank when dumping.
Dump black tank, use tank flusher then dump grey to use it as a semi rinse of sewer hose.
Add some water back into black tank after dumping so bottom of tank stays wet. Stuff won't stick to wet tank.
Don't over think it......you don't when using your toilet/sinks at home.
