# Service bulletin PUB\-190312REV

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

The purpose of this Product Upgrade Bulletin is to inform REV Recreation Group dealers of the need to inspect and, if necessary, correct the routing of hydraulic hoses on certain Class A diesel motorhomes: model year 2016 American Coach American Allegiance, model year\(s\) 2016\-2019 American Coach American Dream, model year\(s\) 2016\-2019 American Coach American Eagle, model year 2016 American Coach American Heritage, model year 2016 American Coach American Tradition, model year 2016 Monaco Dynasty, model year\(s\) 2018\-2019 Monaco Marquis, and model year\(s\) 2018\-2019 Monaco Signature. On motorhomes affected by this Product Upgrade, the hydraulic hoses may be connected to the manifold/pump in a manner that causes them to be too tightly coiled, compressed or obstructed, which may cause the hoses to leak.
