[Fulltiming]

Back in my Airstream days, we had a sewer cap with a hose fitting on it. We could hook up a garden hose to the hose fitting, run it away from the coach and keep the grey water tank open all the time. As late as the early 90's some State Parks (Beavers Bend in Oklahoma being one of them) still allowed you to do that openly. Sometimes we forget that prior to the early 70's many travel trailers (including Airstreams) did not even have a way to store grey water. Grey water HAD to be dumped. If you wanted to 'collect' it, you put a 5 gallon bucket under the grey water drain.
