My 2013 Rockwood 8289WS just got the cracked skylight syndrome...discovered it minutes after taking this picture on our last camping trip. Anyway, I ordered a Lexan Skylight from these guys rather than replace it with another cheap factory one. Replacement RV Skylights from EZ Tops World Wide Inc.
It was less than $100 including shipping. Should hold up better...especially with the care I will take installing it.
I read about the recall but didn't waste my time calling FR, since there was no damage (rot) to the roof and I didn't buy the trailer new.
My skylight had more than half a dozen small cracks each coming from various screw holes. "The" crack extended up from a screw hole almost to the top of the dome. The hail we had just experienced may have extended that crack, but in general the cracks were obviously old and related to improper installation. Some of the screws were rusted and there were a few old dirt trails from water on the inside.
