The link I posted above (http://ultimateclassicrock.com/rolling-stones-mobile-studio/) mentions some of the things it was used for after NPFTD.https://en.wikipedia.org/wiki/Rolling_Stones_Mobile
wiki has NPFTD as the last album recorded on it, and going by that list it was the first time it had been used in 5 years. Although I don't know if that list is complete or just a selection of albums.
EDIT: D'oh! it clearly says that it's notable albums, so only a selection rather than a complete list
The “Mighty Mobile,” as the Stones called it, was retired in 1993 after a final recording by Chris Jagger – Mick’s brother – and his band Atcha! “Around 1992 the truck was bought at auction by an American production company called Loho Studios,” says Tawkin. “It was shipped to New York. Loho made the RSM available for hire around New York City. Most notably it did a short residency at the famous punk bar CBGB’s. Here it recorded live shows from some of New York City’s most infamous hardcore bands such as the Ramones, Patti Smith and others.
