We aren't that far north, but we do the winterize/de-winterize thing as needed. We de-winterized just last week for a 3 night trip where we could find 40 degree days. Re-winterized before leaving the CG. If you are setup right, you can winterize a TT in about 20 minutes. If you blow out the lines, a good bicycle pump is all that's needed. We use RV antifreeze and don't blowout the lines.
