Service bulletin TSB 19-004

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

On certain Momentum Travel Trailer models ( 25G, 28G & 29G) the EMS power shed for the bedroom AC and Water Heater is wired incorrectly. The hot wire is not routed through the current sensor. As a result, the system will not shed appliances as intended.

The document

The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
