I’m having the same issues but I can’t find a leak. The plumbing is a mess under the cabinets in the slide . Main water in ,exterior shower, hot water heater and kitchen sink plumbing are all in the slide. Appears the sink drain is attached with zip ties and had 1 drop of water there but not enough to saturate the slide floor . I’d be interested in what you find is the culprit...
