SarahElizabeth: You will have no issues for short-time freezes. Relax! :)
RE: Dripping Water: We spent many nights in freezing temps over our 16 years of full-timing. We, and everyone in our winter park in the desert of Arizona, were advised to leave the water drip overnight and it seemed to work with everyone - no lines were frozen. During the days we used the water freely so it kept the lines open even if we had freezing days although it usually warmed up to the 40's at least. Of course, you can only do this if you have sewer hookups so your gray tank doesn't fill up.
We never let our water hose outside. We filled our tank and ran off it. The water pump never froze. A frozen water hose takes forever to thaw.
If we'd be staying a short time in a park and leaving the next day, if we had cold weather - not necessarily freezing - we didn't leave our sewer hose out either. Trying to store a cold hose will surely put a crack in it. We kept it stores until time to dump.
