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.

WSB-09
Tiffin Motorhomes issued a technical service bulletin for Open Trail Motorhomes with a 51V battery system and a hydronic heating system. It was found that operating the hydronic heating system on the diesel burner would cause a temporary overload of the electrical system which would shut down. To solve this issue, 2 new DC-DC converters are being installed.
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.
