Bypass hot water tank. Do not put anti freeze in there.
Use compressed air if you wish.
Disconnect and drain all showers ( inside and out )
Then fill system with antifreeze and run each tap till anti freeze runs out.
Don’t forget low point drains and grey and black tanks.
Dump a cup or two into each trap.
I leave all my valves open.

All good points. If you get antifreeze in the hot water tank it’s not the end of the world. I think it’s more of the fact that you would be wasting gallons of it trying to fill it up.
Also do the city fill valve. The check-valve line is where you hook up your RV to city water. It needs a bit of antifreeze too.
Remove the screen attached to your city water hookup. Push in on the check valve inside (some water will spurt out), and hold it down until you see some antifreeze trickle back down that line. Make SURE the pump is off whe you do this one. Trust me. You’ll be covered in antifreeze and you’ll need to replace the guts in the valve.
I have a washing machine in the motorhome. I’ll need to google how to winterize that.
