Newer RVs that are hard to winterize.....grrrrr

I guess I will have to get a filter and dryer. I have a small oil-less compressor but it does not have a tank and I dont think it puts out enough air to blow out the lines. I will still be using the pink stuff at least for the traps, toilet and to draw some into the pump. I dont see how blowing the lines will get the water sitting in the pump out and I like to have a liquid seal in the toilet.
