Just a followup on my passenger side rear bedroom slide leak. I appreciate all the help provided. This leak was not a typical leak - it welled up under the aluminum base supporting this bedroom slide and there was no moisture on top or on the sides of the slide. The moisture would not appear until 20-30 minutes after a rain storm in the vicinity of the engine step-up in the bedroom. After much siliconing and teeth gnashing (and ripping up carpeting) we found the leak source. During the waning days of production, someone forgot to trim the water escape slot on the plastic gasket at the bottom of both furnaces. During a rain storm, especially if the rain was falling directly on the furnace cover, the water had no way to drain to the outside and worked its way along a steel beam into the bedroom and out into the rug. We had a crack in our passenger side living room slide that probably was caused by the same oversight but was fixed when we found someone who repaired the crack. We also went into the front furnace and made sure the water escape slot was sufficiently opened. Hope this helps someone else along the line.
