Well, lets look at HISTORY. Hundreds of Thousands of RV's are winterized every year. They all use what is called RV antifreeze, regardless of the maker. IF ANY of the Antifreeze harmed humans, there would be BIG National news stories every spring. So, do not worry, you will be OK. The Antifreeze is not designed for regular drinking but for freeze protection. The REAL way to de-winterize is to drain and flush and then SANITIZE your fresh water system as ALL the manuals state. They recommend BLEACH (small cup) to sanitize the fresh water tank and systems. Would YOU drink a gallon of straight Bleach? But, RV'ers are always using a small bleach mixture to sanitize their systems. QUANTITY is the real issue here. Too MUCH water will kill you also. RV antifreeze will get slushy below 32 degrees, it will not stay a complete liquid. Doug
