Should you do it now?
I'd say it wouldn't hurt...I did mine tonite because I got caught once and had to put the trailer in a heated shop to thaw it out. Got lucky as there wasn't any damage. That was mid-Oct. My experience is that -10 C is the temp where you'll freeze up quick and have potential issues. Any warmer and it seems to not freeze to the extent to cause problems.
I drain and bypass the h.w.t, use air in the lines, disconnect the pump and run till dry, leave the h.w.t and pump lines unhooked, leave all taps open and pour a few cups of antifreeze down the drains.
Never seen the need to waste a bunch of antifreeze in the lines.
I leave the taps open and the low point drains open on my way to where I store it. I think any water that may have settled anywhere in the system would likely get drained out while in motion. And any residual water after that would most likely evaporate.
Never had an issue with this system.

Now..... if i can only figure out how to keep them flippin' mice out
