The example he gave has nothing to do with the US RVIA sticker program, only the Canadian certification program. In fact, US RV's imported into Canada have to pass their inspection even if they do have an RVIA sticker. He has not shown an example of any US government entity requiring an RVIA sticker. There are several smaller manufacturers, as well as some high end custom RV manufacturers that are not members of the RVIA, and their products do not display the sticker. There are legal requirements for US RV's to meet certain ANSI/NFPA and NHTSA standards, but there is no legal requirement that an RVIA sticker be applied to an RV.
