We keep the gray tank open.
Keeps us from dumping it every 3rd day or sooner with grandkids. 
I close it a couple of days before dumping the black tank, good soapy rinse water. |
I've done the same way for the past 40+ years without any tank issues.
I did however use the split PVC pipe as a tray for the hose with the P trap sag formed as it connected to the rv then laid on the tray at a slight angle to the sewer.
