Well it worked!!! Thanks everyone. I turned the screened washer around as suggested and it immediately started picking up antifreeze. Made sure it came out of each faucets both hot and cold side. Flushed commode and added a gallon to both grey tanks and also black tank. I turned washer on until pink fluid showed it washer tub. I drained the blue and white hose underneath unit Assuming that’s the ice maker drain. Drained both low point valves in convince center. And turned on outside faucet fixtures until pink fluid ran out. Only thing I didn’t see was pink in ice maker But I turned ice maker off and drained blue white line. Hope that will work? Anything else I may have missed.? Sorry first time doing this and first RV.
