I usually spend six months in the RGV of Texas. I leave both the 'black valve and the shower valves closed until the black tank needs emptied. Empty the black tank with the aide of the 'sani-flush' and follow that with the shower/bath tank. This keeps the parks system flushed as well as my own pluming. I leave the tank for the kitchen/galley open.
This works for me and controls any vented odors.
