Standard " Pink" RV antifreeze is pre diluted and is designed to be used full strength and to displace /replace the water .
The - 50 below rating for RV antifreeze is not its freeze point.
The antifreeze turns to a,slush but does not expand and burst water / plumbing lines / valves.
From the chart I saw , diluted RV antifreeze -- 1:4 ratio (water / antifreeze) has a freeze point just slightly below plain water.
We have used our trailer during the November deer hunting season and have used -35 below F washer fluid in the black tank .It's cheaper and does give better freeze protection. If nighttime lows are only slightly below freezing and go above freezing during the the day ,I would not be overly concerned about your plumbing freezing up.
NOTE ** Windshield washer fluid is toxic, so you need to dispose of it properly and only use it in your black and gray tanks.
