Does your RV Antifreeze contain Ethyl Alcohol?

Maybe I've been living underneath a rock, but I didn't know ethyl alcohol was ethanol. Ethanol is widely known to degrade rubber/plastic seals and hoses in older engines, especially older boat engine...

I don't know about in the US, but in CAN if the pink RV plumbing anti-freeze has alcohol in it it has a "Danger Flammable" label on the jug. It's also about 1/3 the price of the other stuff and a more washy looking pink color, but doesn't stain white plastic sinks etc nearly as much. I have been using alcohol based in my RV's for years with no side affects to my plumbing or after taste in water lines.
