The "liquid" in an LCD is not water.
It is N-(4-Methoxybenzylidene)-4-butylaniline
) an organic compound often used in liquid crystals
It has a lower freezing point.
However its operating and storage range is not as low as you might think.
Operating Temperature: 32 - 104 degrees F (0 - 40 degrees C)
Operating Humidity: 20 - 80%
Operating Altitude: 0 - 9180 feet (0 - 2800m)
Storage Temperature: 14 - 122 degrees F (-10 - 50 degrees C)
Storage Humidity: 10 - 90%
Storage Altitude: 0 to 9840 feet (0 - 3000m)
This is why when it is cold out, your car GPS display will not display until the car warms up some and it is solid black and dim in the hot sun.
Having said all that IT DEPENDS on how you store your camper. Is it plugged into shore power all winter to keep the battery charged? If so, you may not need to remove any LCD items from your camper because they have "instant on" circuitry that keeps a level of heat in the item.
So depending on your climate and your risk tolerance, you may not need to remove it at all.
Here in PA, USA I pull the TV but not the ZX-700 for example. The TV is used as a spare in the bedroom (I have the stand for it).
If you kill the master power switch or remove the battery you may be more at risk.
More info to answer the "aviation" comment. Not all LC materials are equal. While MBBA is the most common LC material used in "cheap" LCD TVs, more expensive items can use other LC materials that have lower or higher tolerance temperatures. Some can tolerate temps as low as -40C and as high as 85C (but not both from the same LC medium). See attached Document.
Bluebird's comment is most appropriate. See the documentation that came with your LCD item.
