Well, I must live a charmed life...no stink inside, no stink while dumping, and no stink sitting out side from my vent or neighbors.
Plenty of water and rinsing out the black tank with soapy water from the gray tank every time I dump the tanks, works just fine for me. I too use a clear connection to insure that after I rinse the tank, nothing but clear water comes out.
I also insure that my stinky slinky is firmly attached to the sewer connection either by screwing it in tight, or putting something on it weighing it down if no threaded connection on the sewer opening.
And yes, the cost of those chemicals will add up to hundreds of $$ over the years. But, you're keeping a company in business with pay for the employees.
