Correct procedure for winterizing the van?

[VW_Johan]

Hopefully still a few weeks until we start to get sub-zero temperatures here, but wondering what thoughts you have on winterizing the van, particularly what comes to the water and grey water. Plan to empty the water tank and Truma boiler, as well as opening the two service valves in the utility cupboard. Open all taps (including rear shower) and let drain. And of course emptying the gray water tank. But what more should be done? Should I use low pressure copmpressed air to empty the water lines? Pour antifreeze into the sink to make sure the gray water lines dont freeze? Winter temperatures get down to to -30C where we live so fairly cold. The van will be stored ourdoors under a roof.

Does it make any difference? Last winter we froze the on-board water. A couple of hours with the heater on and it came back to life.
Overthinking?

…….you could pop the washing up liquid somewhere warm, we froze that also!
