I generally drain out the fresh tank via the low point drain, remove the plug in the hot water tank as well and drain that.
Then after putting it all back together, use the blow out plug at the fresh water to blow out the line, and similarly use the plug at the hot water to blow out that line. There are some bypass arrangements such that one can use it just at the hot water tank, but I try not to mess with that!
Then drain out the black and gray adding back tiny bit with that ridex powder dose for the tanks.
Come spring the fresh water tank and lines get rinsed with baking soda, vinegar, baking soda and then rinse again. This also rinses out the gray and black tanks with the addition of a bag of ice in the black tank and a ride on the hood streets to slosh the ice around!
Never had any issues with fresh water system essences now the gray and black tanks! Some of our rigs had heated basements and tanks yet we still did this before storing and bringing em out for a winter trip.
The blow out plug fits the hot water tank drain nicely. We use a plastic threaded blowout plug, rather replace it than the threads on the rig!
