You assume correctly and it does not usually get done, or verified at least by most dealers. I'd double check every wheel. On a new unit probably a good idea to pull each one just for a look.
You can find lots of threads about Nev-R-Adjusts where a spring or the adjuster came off, and the poster instantly jumps to "Nev-R-Adjusts are junk".
Well they're not junk, but if they're way too loose in the adjustment dept and you hit a pothole hard enough its very easy for the adjuster to pop out, followed by a spring or two. We have been running them on tool trailers for about 4 years now and we have never had so much as one issue and our trailers get abused more than most RV's.
