Vehicle report
Technical service bulletins are instructions a manufacturer sent its dealers about a known fault. They are not recalls and the work is usually not free, but they are the clearest signal of a problem the manufacturer already knows about.

As per Lippert Components Technical Service Bulletin 11-004-21. The slide room actuator was assembled incorrectly, which may cause the room to become stuck in the out position and prevent from fully retracting.
Complaint counts are reports filed with NHTSA, not failure rates. A common model collects more of them than a rare one that breaks more often.
