I must be the only odd ball here???
I keep my sewer valve closed, but the grey valve OPEN.. I close it the day before we are packing up. Been doing it this way from day #1, about 35+ years ago with zero issues... No unwanted flies, or smells... That's why we have "P" traps
Gray is less critical as it doesn't have a lot of solids mixed in. But if I'm going out to drain the black, doing the gray at the same time isn't any burden and allows you flush any black residue out of the hose.
agreed.. That's why I close the grey the day before leaving.. that allows at least 2 showers and other misc. grey water to accumulate in the tank to RINSE the tube after dumping black water
