When you call your insurance company to arrange coverage on your newly purchased Ford or GM truck. Ditto if you buy a new Winnebago, towable or drivable. Why? Because they know that those manufacturers build units that are certified to be in compliance with the appropriate safety requirements. There’s no need to ask. On the trucks there’s a compliance label in the drivers door jamb, on the RV’s, there’s a (usually) RVIA seal next to the entry door certifying that the unit was built to the appropriate standards.
The RVIA certification is nothing more than a self-certification: the manufacturer stating that it was built to the appropriate codes. If you build your own RV, you are required to build it to the applicable vehicle and other codes, but there's no requirement in general to have it independently inspected or certified; you may just need to similarly self-certify that you've followed the code. Some states would require more or less inspection by DOT or DOT-approved inspections before issuing tags, or as part of normal periodic motor vehicle inspections, but those are usually more about basic safety and standard equipment required of all vehicles or trailers rather than RV-specific systems. (For that matter, the same basic requirements apply to homebuilt cars.)
There are some campgrounds that choose to exclude homebuilt RVs, just as there are some that exclude non-hard-sided RVs or tents or RVs other than class A motorhomes or RVs older than ten years old or RVs longer than some maximum length, for whatever reason.
