Other CSA-045
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
Tiffin sent out an addendum to be added to Owner's Manuals that states, "Tiffin Motorhomes recommends that all diesel units be refueled using standard automotive-grade diesel fuel pumps, rather than high-flow commercial truck stop pumps. The fuel delivery rate from commercial truck stop pumps is often too aggressive for motorhome fuel systems, which are not designed to handle rapid fuel intake. Using high-flow commercial truck stop pumps can result in overflow, spillage, premature shutoff, or even damage to the fuel fill components."
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.

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