I don't want to dump at my present cg, near Charleston - the water smells like rotten eggs - don't need that on top of sewer stink!!!!!!!!!!!!! So any suggestions to get rid of "peppie la pew"???
I also think your black water level is above the vent opening. If it were me, I'd dump now, put some of that stinky rotten egg water into the black tank to keep things wet, and then dump/flush again at the next campground. If you don't want the rotten egg water in your fresh water system, you can pour a couple of gallons into the toilet with a bucket that you fill outside.
I hope you get the problem resolved.

If the air conditioners are running steady, is there a possibility that the exhaust from the air conditioner is blowing over or down the vent pipe and driving the air back into the toilet when flushing? You might check the proximity of the vent pipes to the air conditioner exhaust. Just another possibility to check. Happy Trails Bert

When you dump, are you opening black first, then opening gray to flush things out once black is done?
That's the most common method.
If that's the way you're doing it, it's the only time that the gray valve and the black valve are both open. With that situation, if you have ANY trap that has dried out, it will allow gas from the campground septic system to flow back into your coach through the vent that has the dried out empty trap.
As mentioned by pacific sun, check washer dryer trap, shower trap and all sink traps. With an empty trap, the only time you wlll get odors is when you're connected to a sewer hookup and both valves are open.
All it takes is one. When we set up, one of the things on our checklist is to run water through every drain, which is shower and 3 sinks for us, because the traps dry out while sitting in our driveway.

A cup or so of bleach in the tank will kill bacteria and odors, but you will lose any digestion going on.
Again I say, you have no digestion going on anyway. Black tanks are holding tanks...not digesters. Digestion additives are a scam.
Unless you monitor dissolved oxygen levels, Biochemical Oxygen Demand levels, floc settling, dissolved solids levels, pH levels, treatment bacteria condition and such...you have no business even thinking about digestion. Lack of digestion is NOT your problem!!
Go with the bleach addition to clean water after a good dump and flush.

myself and a friend of mine have a 1995 and 1996 kountry star a class diesel.
if our tanks are full and we drive away to a dump station our motorhomes start smeling either black or grey water (not sure) but think black.but if we only have say around a 1/4 tank they do not smell while driveing.only when they appear over 1/2 full
any help appreciated.
Just a thought: turn the exhaust vent fan off before flushing.

Not overly concerned about depreciation with this rig...
Just clean your tank out. Just before you leave the campground, flush out your black tank with water several times (fill it ALMOST to the full mark and dump). Then fill tank 1/4 full of water, whole bottle of pine-sal and just before you drive out of campground put two bags of ice down the toilet. When you get to the next campground dump that mix and your tank will be ok. The ice driving down the road helps to remove any hard stuff that sticks to the walls and bottom of the tank.
If you take your rig in for this at a RV service center, the first thing they do is flush out your tank, put 50 pounds of ice down the toilet, drive your rig a few miles around then charge you $80 for "cleaning your black tank" listed on the bill.
