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.
5SF-033018
It has been determined that the sidewall header for the slide room opening is insufficient to support the weight and could over time sag causing a gap in the slide room seal. This gap could allow water penetration.
5SF-032618
Dometic Furnace Limit Switch service bulletin on all Small & Medium Furnaces (AFS, AFM, DFS, DFM). Fiberglass sleeve over the exhaust tube to prevent wire from shorting and blowing protective fuse.
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.
