I use rv antifreeze, but I don't really trust it to get into every inch of pipe, valves, etc in our Lance. Its going down to 5 degf here tonight in Alabama and I will have the camper heat running to keep the camper about 55 degf. Probably overkill but its cheap insurance and I will sleep well. 🙂
I did a couple of tests a few years back by putting a cup of rv antifreeze in our freezer. IIRC it went down to about -2 degf. The antifreeze turned to slush, but never froze solid.

Remember that it does not need to be bone dry to winterize. You only need to blow out the majority of water so that if any remaining freezes, it has a place to expand. I typically set my compressor regulator to 50 psi to prevent over pressurizing the system and do my rounds between faucets and low points until nothing but air comes out. The order you do the blow out depends on the routing of your plumbing and after a couple times doing it will reveal a pattern that works well for your camper.
