It's a nature of the beast, most of us learn to deal with it.
One thing that usually helps ours, when we're leaving a campground, make sure your hold tanks are empty, put about 10 gallons or so of fresh water in the tanks, then about a half bottle of Murphy's Oil
Soap, when you get to the next campground, dump the tank, and flush the black water tank for about 10 minutes or so.
This is not a permanent fix, but it should help.
It involves cutting an access hole in the black/gray tank pan at the valve area, installing the SeeLevel printed circuit boards to the sides of the tanks. Install the monitor panel on the wall. You can get to the fresh tank side below your closet floor. You can us the existing Micropulse wiring, so at least that's a plus.
