Just had a brainstorm - how about a survey!

I use to use the pink and bleach the lines in the spring. Then we bought another camper that we leave at the lake and our big one for work and play. So we go up in the winter and other times of the year if its nice we hook up the water and use it for the weekend and blow the lines and drain the water heater. would use to much anti freeze there have never had any problems so started doing both campers that way. Bought a couple of small air compressors at tractor supply for $50 each and in 3 years they have paid for themselves in anti freeze and time messing cleaning every spring.if your worried about oil or other stuff in the line just let the water run for a bit at the first hook up we put bleach in our FW tank anyway every time we use it and the one at the lake has full hook ups. So Blow and drink.
