I was hoping more people have had this problem and could say if the manufacturer had a recall. I checked my warranty and it says 2 yr from purchase date.Sounds like a structural defect (I know, not what you want to hear) and you can fix the fiberglass, get a fairly close paint match, but the crack will likely reapear. I’d say its a question for the manufacturer - see if there is a factory fix. They’ll probably say this is the first they’ve ever heard of such a thing, but if its a construction deficiency, there have probably been others. Can you post some pics?
And the manufacturer should stand good for itIt is a common issue across all manufacturers. When they cut the hole in the fiberglass for the slide they usually cut rectangular corners. The 90 defgree angle at the corner creates a stress point and as the unit moves down the highway a crack can appear starting at that corner. The solution is to use rounded corners instead of square corners.

It is a common problem, but! The square corner is???? I say that because my 73' silver liner had a round top door that had a stress Crack along the large roughly 1ft radius.It is a common issue across all manufacturers.
