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.

Under certain circumstances the vehicle may lean to one side while empty due to the location of the internal equipment. While this is accounted for during the design, Forest River - Coachmen has developed a shim kit to remove any lean for an owner.
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.
