Simple trick ?
Never dump on the way out of a CG !
Never dump till after driving a few miles, and around a few corners.
Easier said than done. Dump stations while on the road are not readily available. Some RVs are built so cheaply these days, the blank tanks can't hold the load during long distance travel. (broken plumbing connections and even loosing a tank, while not common, has happened)
You do make a good point though. That is why I see some RVers emptying their holding tanks upon arrival at their new destination rather than upon leaving the previous campground.
