Conversion Vans not allowed at some RV Parks?

In some states, RV's require special license plates and motor vehicle tax payments. That may be how they check instead of RVIA. You should check the state you register your van in for the laws and the difference between conversion vans and other kinds of RV. You'll probably never get caught, but may want to verify, especially for insurance purposes.

I may be wrong, but I don't think RVs generally require special plates, at least many kinds of RVs. There's nothing preventing one from registering a motorhome as a truck or bus; but in many cases it would be more costly, would cause one to need to stop at weigh stations, may force one to obtain a CDL, would cost more for insurance, etc. etc.

Similarly, a towable RV can be registered as a generic (utility) trailer, so far as I know, and not as an RV. In some states there may not be a distinction for trailers, at least for smaller ones.

There are specific requirements for things to be registered as RVs in terms of specific equipment, and in return you get "perks" like more lenient licensing requirements, lower insurance and registration rates, the magical RV registration that some campgrounds may require, and the like.
