Could it really be this easy?

I have had RVs since 1969 and always had the black tank empty over the winter. I had a stand-alone ice maker in my Mountain Aire and only drained the line to it. It makes ICE!! Don't put pink stuff in your ice maker . It will remove a coating on the partitions and make it hard to get all the ice out. I do mine with 1/2 gal. of pink and the air compressor an have been doing that for many years. It does get cold here, -10F is not unusual in Jan-Feb.
