Generally, dissolving stuff in water lowers the freezing point and raises the boiling point. That's the basic idea for how antifreeze and road salt works. That being so, it's really hard to predict at what temperature some water based product might freeze. Nearly all other substances do not expand when they freeze; water is quite unusual in that regard.
Plastic bottles generally won't be worse for the wear if their contents freeze; they have enough give to take up the expansion. Cans may be a different story, and glass containers definitely are. Oils and solvents and alcohol (and indeed most liquids) don't expand when they freeze, so regardless of their freezing point it's not a problem to leave them in the RV.
I usually find it's easiest to just collect all the cleaning supplies and whatnot and bring them in for the winter, even if it's not strictly necessary. Things like engine oil, antifreeze, and winter rated windshield washer fluid which are in the vehicle systems over the winter are of course safe to leave in the cold; if they froze, then the vehicle couldn't possibly work in cold weather.
