Holding tank odor

Am newbie to forums so thanks in advance for any help. I have read all posts that come up under "odor" search. No help so far. Have any of you seen or heard of this problem? When I look into the black tank through the open flush valve the inlet pipe (that extends down from the floor flange) seems to extend too far into the tank. When the tank is about half full the effluent covers the end of the inlet pipe. I bent a coat hanger wire into a tight "J" shape with about 4 inches curved back up and probed the inlet. I was able to confirm that the inlet pipe extends at least 4 inches into the tank or about half the depth of the tank. When the liquid gets up to that depth the odor is impossible to control. Has anyone seen a black tank inlet made like this? I suspect sloppy assembly since their was plenty of it in other areas of this 2008 Georgetown 357 quad slide class A. Any thoughts on a solution? Thanks...gtj

That being the case, can you just not take it all apart and fix it like it should be?
If what you're saying is true, then it can't hardly vent, no matter where the vent pipe might be.
All else fails, you'll just have to dump more often and even though waiting for a 3/4 tank is best. If you have cleaning nozzles installed in the tank, so much the better.
