Service bulletin 7SB005-26-01A

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

Winnebago is implementing an improved sealant application process to enhance durability, long-term maintenance, and vehicle appearance. Moving forward, SikaLastomer®-714 will be used as the sealant for roof-mounted components, including roof vents, skylights, and TV antennas. This change eliminates the use of self-leveling sealant around roof components, providing a cleaner, more refined appearance while reducing concerns related to cracking or discoloration commonly associated with traditional sealants.

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.

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