Winterizing the line from the Alde to pressure relief valve

I winterized my 2024 320. Drained everything. Blew out the lines with nautilus knobs turned to 45 degree angle and ran antifreeze through all the lines. All good. I read somewhere to leave the Alde pressure relief/drain valve open for the winter so did that. Then yesterday I but the camper on jack stands for the winter. While jacking up the passenger side some water dripped out of the Alde drain, not much, dripped for a few minutes. So got me to thinking. Do I need to blow this out again, how would I do that after winterizing? How does the line between the Alde and drain valve get blown out to begin with?

    The trailer does not have to be dry as a bone to be properly winterized. A few drips from the bottom of the Alde (through the yellow valve) is not an issue at all.

    There is always a ton of confusion about the "blow out" instructions on the Nautilus trailers. With the handles at the 45 degree position, the only place in the trailer being "blown out" is the Nautilus harness behind the Nautilus panel. I have no idea if any compressed air gets anywhere else in the trailer except for that "harness". All of the winterizing instructions from the Nautilus 3.0 manual show the "Red" handle preventing anything (including compressed air) from getting to the Alde hot water tank.
