Service bulletin TSB 21-02

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.

NHTSA's summary

The steel tube backer in the coach floor may not have been installed in the correct location to adequately secure the gray water holding tank underneath the 2021 24.3 Axis & Vegas motorhomes. This procedure is to be used to add a ā€œZā€ bracket to the bottom of the rear-most cross member in the chassis of the 24.3 Axis/Vegas product. This new bracket is intended to replace the ā€œZā€ brackets that are currently installed near the top of the tank above the cross member because of inadequate backer in the unit floor

Listing a model year does not mean every vehicle of it is concerned: the document says which.
