2017 Cherokee 26dbh slide leak

[Mike26]

Our Grey Wolf is leaking in the slide box when the slide is in. The leak appears to be coming in from the floor and even below. I have disassembled the dining table and bench and cut the floor (without damaging the polyethylene sheet). The water is still entering the floor of the slide during heavy rains, with the slide in. Interestingly enough the water is below the floor and weeping on the polyethylene sheet and the bottom side of the floor. It is enough water to saturate the floor and drip onto the main floor. The only place I can see on the outside allowing water in is the lower 4" aluminum trim. It's seal to the sheet metal is not pristine but the narrow mate doesn't look enough to allow that much water. Has anyone seen this leak on a 26Grey Wolf?

Time for an assistant. One of you is outside with a garden hose and nozzle. He concentrates on a small area. The other watches inside. If no water, the outside person moves to the next spot...
