Based upon experiences with my '64 Overlander, if you haven't been encountering rain that may be entering through a number of potential places in the rear, I would be suspicious of the following:
1.) The bathtub/shower drain fixture. Some of these were cast iron, and when subject to decades of use and rust, they begin to self-destruct. The one on my Overlander was one of my earliest leak problems in 1995.
2.) The junction point where the shower/tub drain join with the other gray water points on that side of the coach - - inadequate winterization resulted in freeze cracks on mine - - these were also discovered during my first year of ownership. A part of this assembly must have been problematic for quite some time as a two flexible plumbing couplers had been placed in these lines (by appearances shortly before my purchase of the coach).
3.) The tub fill/shower valve. This was the culprit of much of my continuing problem as it was only evident after heavy use of the shower/bath. The original fittings on the back of the faucet assembly had been subject to freeze damage at some point in the past, and the cracking caused mutiple points for leaks - - it probably would have been much more noticeable had I been using the demand water system, but this was during my first year of ownership before I had that system operational (cracked tank and missing pump).
4.) The trap for the bathroom vanity could also be a potential source, but it is one that I have not had problems with at this point.
5.) There are also potential culprits that can be examined from the one-stop service center such as the:
A.) City/Demand systme selector valve. This valve was one of the early leak producers on my coach (probably another freeze victim).
B.) City Water pressure regulator. This valve can leak due to a number of issues, and is one that often causes problems, but usually it appears as a leak from a tube exiting the belly pan.
C.) Low Point Drain Valves. There may be from one to several in the rear of the coach. These are potential freeze damage points as well as wear factors from valve failures (three of these valves failed from age on my Minuet this season).
D.) Just about any of the water supply lines in the rear of the coach are suspects with this type of water appearance. They can be pin hole size problems to much larger splits.
E.) The water heater is likely in the rear, and if original it could have leaks in the nearby water lines or the tank could have one or more pinhole leaks.
There is rarely only one potential culprit of such moisture problems. Any plumbing supply or waste line is a possible suspect. Methodical inspection is probably about the only solution. If you are experience frequent rains, the potential sources are even greater as then you have seams in the skin as well as any point of penetration of exterior panels - - my most memorable problem of that type was the center clearance light that seemed to resist every water proofing effort until I had the exterior polished and Plasticoated - - the leak has not returned for the past three years.
Good luck with your search for the leak culprit!
