(2) to examine and copy any documentary evidence of any person having materials or information relevant to any function of the Secretary under this chapter;

(3) to require, by general or special orders, any person to file, in such form as the Secretary may prescribe, reports or answers in writing to specific questions relating to any function of the Secretary under this chapter.

The Secretary shall disclose so much of other information obtained under this subsection to the public as he determines will assist in carrying out this chapter; but he shall not (under the authority of this sentence) make available or disclosure to the public any information which contains or relates to a trade secret or any information the disclosure of which would put the person furnishing such information at a substantial competitive disadvantage, unless he determines that it is necessary to carry out the purpose of this chapter.

(d) Refusal to obey subpena or order of Secretary; order of compliance by district court; failure to obey order of compliance punishable as contempt
Any of the district courts of the United States within the jurisdiction of which an inquiry is carried on may, in the case of contumacy or refusal to obey a subpena or order of the Secretary issued under paragraph (1) or paragraph (3) of subsection (c) of this section, issue an order requiring compliance therewith; and any failure to obey such order of the court may be punished by such court as a contempt thereof.

Each manufacturer of manufactured homes shall submit the building plans for every model of such manufactured homes to the Secretary or his designee for the purpose of inspection under this section. The manufacturer must certify that each such building plan meets the Federal construction and safety standards in force at that time before the model involved is produced.

(f) Records, reports and information from manufacturers, distributors and retailers of manufactured homes; inspection and examination of relevant books, papers, records and documents by designated person
Each manufacturer, distributor, and retailer of manufactured homes shall establish and maintain such records, make such reports, and provide such information as the Secretary may reasonably require to enable him to determine whether such manufacturer, distributor, or retailer has acted or is acting in compliance with this chapter and Federal manufactured home construction and safety standards prescribed pursuant to this chapter and shall, upon request of a person duly designated by the Secretary, permit such person to inspect appropriate books, papers, records, and documents relevant to determining whether such manufacturer, distributor, or retailer has acted or is acting in compliance with this chapter and manufactured home construction and safety standards prescribed pursuant to this chapter.

(2) the first person who purchases a manufactured home for purposes other than resale, at the time of such purchase or in printed matter placed in the manufactured home.
