# Service bulletin TSB 20\-02

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.

- Type: Service bulletin
- NHTSA id: 10172132
- Published by NHTSA: 2020\-03\-06

## NHTSA's summary

A topcoat sealant was provided by our vendor that did not meet Thor Motor Coach's standard for performance. This was used on 2019 \& 2020 Magnitude and Omni Motorhomes. If the primary sealant does not provide sufficient coverage, the cabover window may experience water intrusion. The repair will be to remove the existing topcoat sealant and apply the proper urethane sealant.
