Wayne,
See link below.
I had been on here awhile back discussing this issue. My leak was not caused by the plumbing but rather the door/glass enclosure system. Water would show up in my lower storage and on the floor.
I took it to my dealer at first and they jacked around with it and said it was fixed. I messed up there by not going out with a rep and testing. Shame on me for taking their word that they had.
I must clarify that I'm not having any issue with the fiberglass portion.
On my next trip it leaked again. I contacted FR this time and they said they had a known problem with their previously manufacturer for the enclosure system. This time I went to a different dealer and had FR ship the door system to them direct. They installed the new system and also said they had tested it. Again I also took their word for it. I think I learned something here.
Next trip out it held up better but eventually I had water running out of the aluminum extrusions at the corners of the glass. I'm guessing that the water is more or less filling up an area then running out.
I haven't seen what a cut section looks like through the aluminum and glass system but obviously it doesn't seal properly.
What I plan to do is cut off the interior excess rubber that is visible around the glass and lay a bead of high quality mold resistant sealant in this corner as well as any other areas that look susceptible to leaks. Another idea is to drill a few holes in the exterior side of the lower aluminum frame piece. I think this would allow me to direct the water out to where I can see it if it leaks again.
It will not be back to the dealer for this issue!
