Letting us know you specific coach can help us help you... Things like an extra dump valve, etc are unique to specific coaches.
Typically the separate dump tanks are plumbed to different fixtures... so no switching of tanks...
The gauges are notoriously bad - often read at least partially full when empty.
If the tank is on the far side from the dump hookup - look for that extra dump valve near the tank (allows keeping the under rv dump line empty in colder weather...)
