Not worried about anti-freeze because I never, ever, ever drink any of the water that comes out of the RV. I only use it for washing, flushing, etc. I retired from the private aviation business and one of the common things among pilots and flight attendants is to never drink the water...even if the airplane is brand new. I'm pretty sure the airlines make coffee from the onboard water supply. Never drink that stuff either (it even has a bad odor).
At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.
