When the winter comes in, i winterize my 31' Dutchmen with rv antifreeze. the problem is when we want to go camping on Thanksgiving and Christmas (My wife is a school teacher and can't be out of work) I have to flush my lines and at the end of the trip, i re-winterize with antifreeze. Some one told me to blow out my water lines with air. Will this work and any idea how to go about doing it.
