Gray/Black Tanks and longer term storage
What do folks do to their gray and black tanks when putting away their camper for long periods during warm weather (I know...HERESY!!)?
We always do 2-3 flushes when dumping black after campout. But surely some residue probably persists on tank sides, etc. And we've had odors from gray after trailer has sat for a month so we need to get a better system.
Should we leave some water in both black and gray with some kind of chemical?
Worried that there could be seals that dry out due to summer heat and evaporation. But we also want to avoid any stagnant water in tanks and smells (which is why I was thinking storing clean and dry might be better).
Appreciate hearing your experiences.
