When to winterize

I have two sets of drains on each side of the RV. Our shower is on the entry side and all other fixtures on the other side.

If I drain those it gets most of the water out of the lines in case we get a short freeze but not all the water drains completely so when we're done for the season I'll blow the lines out with a compressor and then add antifreeze. If I think we'll squeeze out a couple weekends in November I might not add the antifreeze and just blow out the lines.

The fresh water tank is easy to drain because it has a separate valve for draining.

The waste tanks get drained every time we use it so those are never a concern.

The hot water tank can also get drained pretty quick if I get nervous.

The traps don't worry me until we get daytime temps below freezing.

In other words I semi winterize if we're going to keep using it late into the fall, enough so I can finish the job pretty quick if the weather changes fast.
