I have been working on the water control box, it essentially is a box that contains the wast tank dump controls and the water inlet valves.
The "freshwater inlet" also doubles as the water inlet for the truck. it has a valve between it and the fresh water tanks that switches off when the tanks are full.
The "wast tank rinse" feeds water to a sprinkler system within the wast tanks to flush them out.
The "Filter Intake" allows me to suck water from a river etc and filter it via a 3 stage filter system a reverse osmosis membrane and a uv sterilizer.
