So freezing causes delamination?????
If the OP wishes to be careful he can leave the thermostat set to the lowest possible temperature.
Realistically even an RV that is not designed for cold weather use is fairly safe at 25 f (-4 c), so long that is a low temperature for the day and day time temperatures are well above freezing.

Yes, you risk damaging the water lines. The risk is directly proportional to how cold it gets for how long. Even 30° for one hour can freeze those tiny lines. Will that damage them? Who knows. How about providing some supplemental heat, or blowing out the lines but no antifreeze? Or just wing it. The risk is pretty low, but the other side of the coin is it could result in hidden damage that causes big problems like delamination down the road. No easy answer. Easy for me to say take a chance cause it ain't mine to pay to fix down the road. So do you feel lucky today?
Yes, frozen water lines can cause hidden damage that can lead to delamination. I'm surprised you of all people didn't know that. Or maybe you was just reading out of context?
