Here's what RVIA has to say about NFPA and other standards. Maybe try contacting them? They have no authority to enforce NFPA 1192. What they say is "The primary goal of the Standards Department Inspection Program is to monitor the pledge of member manufacturer’s to build in conformance to these adopted standards.". In order for a manufacturer to get the RVIA seal, the manufacturer "certifies" compliance with 1192. "Certify" or "pledge" is more like a "cross my heart, hope to die" promise that doesn't mean much.
I've found a lot of things that don't comply with the NEC that would never happen or be allowed in building construction. I have to think RVIA's "Inspection Program" is a smoke and mirrors program.
