Likely 3-4 gallons. I open low point drains, blow the lines out and keep the inside around 68 during the winter. Close the low point when blowing out the lines, do one at a time about 45 lbs pressure. I use a small heater inside. I don’t use the antifreeze in the lines, only in the drains. Just enough to fill the p trap. My drains should be good with the inside temp but just to be safe.
If you park it at home I would keep it warm inside during the winter.

40 foot class A. I also blow the water from the pipes using compressed air. I do that to reduce dilution. I then follow with "anti-freeze". With 1.5 baths and a clothes washer, I use 5 gallons.

FYI... RV "anti-freeze" does in fact freeze, but when it does, it does not swell-up to burst the pipes.

That's all I've ever done to include draining the water heater. Doing two rounds @ 30-35 psi, letting the lines pressure up then opening one valve at a time until only dry air is coming from the outlet. A few pints of RV antifreeze in each p-trap and it's all good.

Yes drain the water heater as well.

Amounts of antifreeze used can be from one to five gallons depending on RV size and preferred method and is once and done for the season. No need to subscribe and save.

Some people like to fill all water lines with antifreeze. You can do this with a bypass kit that installs on the inlet side of the 12v water pump so the antifreeze can be pumped dirctly from the jug to fill one line at a time. A helper is useful to let you know when antifreeze comes out of the taps. Once done, put about two cups of antifreeze into each P trap. Others use a hand pump (comes with fittings) to connect to each faucet to fill in the reverse direction.

I use compressed air, antifreeze in P traps and washing machine per Splendide instructions; about one gallon.

I use one gallon.
Here is my procedure:
Open all drains including the water heater and drain full system.
Close all the drains and replace low drain plug
Hook up my compressor to the fill valve and open and turn air on @ 20 # pressure. I open faucets and blow out lines. I do move from faucet to faucet throughout the coach after initially having them all open. When completely blown out I disconnect the compressor.
I open all faucets and remove the heads on the kitchen faucet, Shower Head, toilet sprayer head, disconnect water and ice lines on the fridge as well as the main water line feeding the fridge and remove the fridge filter, I leave the water heater tank plug loose. I disconnect the lines to the water pump which on my rig is very accessible.
Last step I put antifreeze in the sink traps and some in the toilet bowl.

I do not put any Antifreeze in my tanks as I do not want the residual taste

Make sure all black and gray water tanks are empty
