Jim,
I have seen some gray (or wash water) tanks
installed. Each one is unique. Instead of a tank I am planning on
installing 3" pipe below the belly to direct the flow more towards the middle of
the trailer where most campground sewer connections seem to be located these
days. While doing this I will snake the pipe around a bit to obtain a modest
amount of storage for the wash water. I am expecting to get 5 to 10 gallons,
which will be plenty for our usage.
