I have a 2016 Fleetwood Storm 35 SK. We had a hard rain about 2 weeks after we bought the unit. It had rained before, but this last time ti came down real hard. We had water running across the floor forward of the bed. When the rain stopped, I went out and inspected the slide. The forward seal on top wasn't covered by the top seal allowing water to come in past the seal. I made a 6" piece of seal, covered the top of the forward seal and no more leakage was noted. Hope this helps. Ray
