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.
22V 584
Due to notification from Manchester Tank, the manufacturer of the LP tank, and a bulletin from RegO, the manufacturer of the LP tank service valve, Newmar has issued recall NHTSA #22V 584 and TC# 2022-550.
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.
