I just had our Class A winterized and was wondering why could you not just blow out all the water lines and make sure you have "NO" water in the RV during the cold months? Yes, I am new at Rving. Gues...
I look at this way. A couple of gallons of RV antifreeze is cheap insurance (<$20) against plumbing problems come spring. A co-worker of mine blows out his mh every year and every spring takes it to CW to fix a plumbing leak.
He says he can never get rid of the 'pink stuff' taste. So he just pays to fix his plumbing every year. :h
