When can I de-winterize my trailer?

It has been warm down here in the SE, got me thinking when do people normally de-winterize trailer? Itching to get on the road…

I would when the average temperature is above freezing. As long as you don’t have a deep freeze, being slightly below freezing at night for a bit won’t necessarily cause the lines to freeze hard.

South of say Tennessee, I would assume you are fine by mid February. Worst case scenario if you are really worried and keep the rig plugged in, turn the heat on really low if you have a cold snap.
