Actually, it is MCA 50-60-402:
" 50-60-402. Factory-built buildings and recreational vehicles to comply with standards. (1) A person, firm, or corporation may not manufacture, sell, or offer for sale any new factory-built building unless the factory-built building and its components, systems, and appliances have been constructed and assembled in accordance with the standards defined in this part.
(2)?A factory-built building that has been approved by the department is considered to be in full compliance with the standards and rules prescribed in parts 1 through 4.
(3)?All factory-built buildings approved by the department are acceptable as meeting the requirements of parts 1 through 4 throughout the state of Montana without further inspection or fees except for zoning, utility connections, and foundation permits required by local ordinance.
(4)?A person, firm, or corporation may not manufacture, sell, or offer for sale a new recreational vehicle unless the vehicle has been constructed and assembled in accordance with the American national standards institute ANSI/A119.2 standard for recreational vehicles. The department is not responsible for enforcing the compliance of recreational vehicles with the ANSI/A119.2 standard as part of the state building code."
I don't see where it states that it is illegal for an RV park to allow a home-built RV to connect to the power pedestal.
Note that "The department is not responsible for enforcing the compliance of recreational vehicles with the ANSI/A119.2 standard as part of the state building code."
It appears that "the department" really doesn't much care what RV builders do!
