A daily walk around of your RV is important so you can spot any trouble or potential problems. For example: the other day I was draining the gray tank, which I do every couple of days, and after I finished I continued around the coach looking for any abnormalities. On the opposite side of the rig I noticed that there was some water dripping out of the RV water heater access panel.
Upon opening the water heater panel I discovered that the drain plug was seeping. Maybe I didn’t tighten it enough the last time I did my purge of the tank.
