Leak near pantry cabinet on my 2008 17c

[ScottM123]

Hi Everyone, I'm hoping someone has expertise here and can give me a heads up on what might be happening with my unit. We are noticing a wet spot on the floor of the pantry cabinet, and I don't believe it is from a roof leak where water might run down the wall in that corner, because we have paper and cloth things packed on the pantry shelves and they would have gotten wet too. In the bottom section, there is a false panel against the wall, and the sink water lines run behind this panel, and I'm wondering what else is there? The panel is only the height of the bottom section of the pantry, as the rest of the cabinet is full depth. So my question is, has anyone removed the false panel, what is behind there, and could there be a split hose or something that is causing the problem? I'm not sure I can remove the panel easily without damaging it, it looks like they have about 15 nails on each side holding it in. Any suggestions would be much appreciated. Thanks for any help...

I used to have a Jayco 17c that did something similar. During rain, I would find water at the rear in the pantry/closet. Turns out, water would get under the tail light cover because they weren't sealed, and water got in where the wiring came through the trailer walls. I actually found the tail light half full of water during a storm one time, which is how I figured it out. Sealed up the top of the tail lights with a small bead of silicone and the problem went away. Worth a look.

If it is the tail lights also drill a small hole in the bottom of the lens cover, so it can drain.

I am not familiar with your 17C, can you post a few picture of the area, including the false panel. Often the false panels are held in place with one or two #2 square head screws. You might be able to feel for the screw locations, end (with some challenges) place a screw driver on the head and remove the screw(s).

The tail lights on our X23B are open on the bottom and will not hold water.
Near our pantry we were also seeing a small puddle on occasion. It was the removable section of water line where one would put the under sink filter (which I don't have). Took a year or so before it started leaking so I guess riding up and down the highways caused it to loosen. I put a little "tighten-up" on it and it hasn't come back. If you can't find anything wet where it could be coming from put some TP sheets or paper towels on the water line joints and in strategic locations on the floor to help locate the source.

Thanks for all of your suggestions, it turns out that I have the open-bottom type of tail lights too. After posting this, we went on a trip and my wife noticed a drip outside the coach near the wheel well, and we traced it to under the kitchen sink! I still have to take a panel off that is stapled in place, but I think we've found our problem. Glad it's not a roof leak! Thanks for your help!

If it is like the panel in my 17Z it merely covers the sink trap and plumbing. I'd take it out and see what is going on behind it.
