For a few hours barely below freezing at night, I wouldn't worry too much. The RV interior probably won't even get below freezing--it's somewhat insulated, after all. I know the interior of my motorhome typically is five or ten degrees above the ambient outside temperature in the early morning hours while sitting in the winter weather without heat.
It wouldn't hurt to drain the water out of the black tank, particularly if it's openly exposed. The tank itself would be okay if that small amount of water froze; however, the piping between the tank and the drain valve could burst, particularly if there's anything much to it and if it dips well below the bottom of the tank.
Of course, feel free to balance my (and anyone else's) advice out with the knowledge of which of us will have to deal with an problems....
