I have the 20 foot hose and a different color hose for the wash out part of the chore. Too much is better than not enough especially if trying to hook up when its getting darl out.
What is disgusting was to watch some campers take the hose they hook up for the black water tank rinse and spray it off right next to the water lines since most water and sewer lines are in the same area at campgrounds.
Its why next year I'll take some bleach along in a bottle to rinse off the tap real good.
The management system linked is looking good as well.
I often wondered about someone in a road side parking lot walking by and pulling the cap and handle to get that last bit onto the pavement being a smart a##.
