Help, water leak

2002 Monaco Windsor 40PBT ((RR8S)
I have water dripping down the inside surface of the rear cap almost center..
I first thought it was a washer leak, but behind the washer is dry.I can see the fresh air intake pipe for the engine goes up through that space.. Does anyone know, is there water lines running in the space between the rear closet wall
and the rear cap??

First guess would be rear marker lights.

Having dealt with similar situation may I suggest to take a closer look at the roof tape between rear cap and the roof. There is a so called roof tape there and if you see any gap than that is where water is coming into. I would not also discount area where gutter meets the cap and the roof. In that are use pure silicon – on the roof use good roofing tape – the one for metal and fiberglass. At the edges use f.e. Sikaflex-715 – it is a self-leveling sealant – you can buy all of this at any good RV supply store. It took me 2 years to eliminate all leaks – last one got me mad. I even suspected escape window in the rear. Sealed many times and water was dripping from the bottom. Finally I noticed that slide out wall was not sealed to slide out frame – pushed inside, cleaned and glued using 100% silicone – so far is working. No more leaks.
Good luck

Had an RV repair tech in Canada tell me that I could use almost any self-leveling caulk. I had purchased several tubes at another RV dealer ($13.95/tube), so this was good news. I carry several tubes at all times. Bought my latest half dozen tubes for $.99 at a railroad salvage discount place in Indiana. I've found that slight cracks in the caulk over awnings can also cause pretty good leaks. Check on the top side of the awning and if there is a crack, fill 'er up! Silicon or self-leveling doesn't seem to make a difference. The self-leveling will seep down into the crack and fill it from the bottom. The roof joints I cleaned out at re-caulked two years ago; made a big difference, but water leaks seem to develop along the way. Even a very small crack in the caulk can lead to a leak. Good luck
