"This vehicle conforms to all applicable US Federal motor vehicle safety standards in effect on the date of manufacturer."

See 49 CFR part 567, vehicle certification/modification.

Yes but owners are not prohibited from modifyiont their RV in the US. They just need to be sure to always go up in component strength.
