I guess there are 2 camps of thought.
Blow out
Anti-freeze.
I'm in the anti-freeze camp as the pump does most of the work.
My last camping of the year I triple flush the black tank.....dump it and then add 10 gallons of water and some laundry soap....drive around the park a bit....dump it again. Add another 10 gallons of water and drive around again....dump it....and then open up all the low points, drain valves, and tank valves, remove the hot water tank anode and drive home.
The action of driving at 60 mph will suck everything out of pretty much everywhere.
And then 5 gallons of anti-freeze flushing through the complete system....nary a problem.
