What must be maintained according to regulations that inspectors can review?

The correct choice is the requirement to maintain all operational and safety documentation. This is crucial because, in the context of manufactured home dealerships, adhering to safety and operational standards is essential for compliance with regulations and ensuring the well-being of customers. Inspectors must have access to these documents to verify that the dealership is following the necessary protocols, which can include things like maintenance records, safety checks, and operational procedures.

These types of documentation help ensure that the manufactured homes being sold or leased meet the established safety regulations and operational standards, thereby protecting both the dealer and the consumer. Having a comprehensive set of operational and safety records reinforces accountability and transparency, key components in maintaining trust and reputation in the industry.

Maintaining only financial records, sales contracts, or lease agreements would not encompass the full scope of compliance expected by inspectors, who need to assess whether operational practices are safe and in line with regulations.
