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.
1STTSB1929082022
In certain model year 2021 & 2022 Basecamp 20 travel trailers, the battery box lid gasket was not installed. In certain situations, the batteries may have the potential of outgassing, and without the gasket, the gases may enter the living area of the trailer.
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.
