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.
VSB-06
It has come to Tiffin Motorhomes attention that Vanleigh Ambition 5th wheel RVs were built with a double axle equalizer instead of a triple axle equalizer. Tiffin Motorhomes will replace the double axle equalizer with a triple axle equalize at no charge to the customer.
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.
