Best way to winterize yet still use unit in winter?

This is how I do it. I blow out the lines getting most of the water out. Pump in the antifreeze, and then blow agian catching the antifreeze. Pour a little antifreeze in the pee traps. I use the same antifreeze over and over. I do this seveal times a year. Should not have to winterize till after Thancksgiving. March is a crapshoot, we park at home so we can and do heat in late March if needed. YMMV
