Freeze damage to yer Mopar?

Yes.

You've got anti freeze in it and it says only 29 degree low for an hour.

It's got to be low 20's for sustained period of time with no antifreeze.

fill a plastic jug with 100% water outside and in the morning at daybreak there will be nothing more that frost on the outside from the thin layer of condensation.

Well, I'm outta the Tampa St Pete area a Lil. 16 miles s of Zephyrhills... a bit cooler. But after losing 2 good Bros and Neighbors, in a fire next door, then having to dig thru the ashes for the man's Father, to have stuff for the Grandson. I'm good with no light. It's unplugged .
