After spending many years winterizing with the pink stuff I bought a lightweight air compressor with a regulator that I could adjust to about 55 psi.
Now, I just empty the tanks and water heater, bypass the water heater, as usual, and hook up the air to the RV water inlet. Then, I just walk around opening each hot and cold valve (one at a time) and let the air run until the lines are each dry.
I do pour a little pink antifreeze into each drain trap and into the washing machine to pump it through the washer pump.
I do have a refrigerator ice maker that I have to disconnect ant blow all of the water from the lines. This, I would do anyway, as you never want to let that pink stuff get into your ice maker.
Besides being cheaper, I feel that this process is far easier than my old antifreeze method.
