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.
76-01
On certain Winnebago vehicles with Winnebago manufactured poptops (60A & 60C), incorrect rivets may have been used during poptop assembly and the poptop overhead brackets may have misaligned rivet holes. Repair involves the replacement of these brackets and rivets with those provided in the kit.
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.
