2017 Lance 1475 trailer leaked around the Fantastic fan during the first heavy rain. When I checked the roof I discovered that the entire roof is recessed lower than the sidewalls and the entire roof was covered to a depth of 3/8".
Lance says to store unit off level to drain water but that won't help when using the trailer. Any designer should know that water can't go up hill so it has to sit there looking for a place to run inside the trailer.
Lance is going to look at my photos of the problem and get back to me but I see others have the same issue. I would carefully check the roof before buying a Lance 1475.
