This puts a few gallons of water into the black tank, so I just have to squirt some Dawn into the toilet (after I get out of the way) for the next cycle.

If I'm at a site that has a sewer connection, then I do the flush cycles as needed until I get a relatively clean flow.

How do you flush the black tank at a dump station? I have not traveled out of state much, but in Virginia, all you get at a state park dump station is a spray nozzle to rinse out the sewer hose. It doesn't have a hose connection I can connect to the black tank flush. I can flush at the camp site prior to departure, but not sure how to flush at the dump station.
