Wash. Rev. Code § 46.70.075
Before issuing a manufacturer license to a manufacturer of mobile homes or travel trailers, the department shall require the applicant to file with the department a surety bond in the amount of forty thousand dollars in the case of a mobile home manufacturer and twenty thousand dollars in the case of a travel trailer manufacturer, running to the state and executed by a surety company authorized to do business in the state. Such bond shall be approved by the attorney general as to form and conditioned that the manufacturer shall conduct his or her business in conformity with the provisions of this chapter and with all standards set by the state of Washington or the federal government pertaining to the construction or safety of such vehicles. Any retail purchaser or vehicle dealer who has suffered any loss or damage by reason of breach of warranty or by any act by a manufacturer which constitutes a violation of this chapter or a violation of any standards set by the state of Washington or the federal government pertaining to construction or safety of such vehicles has the right to institute an action for recovery against such manufacturer and the surety upon such bond. Successive recoveries against the bond shall be permitted, but the aggregate liability of the surety to all persons shall in no event exceed the amount of the bond. Upon exhaustion of the penalty of the bond or cancellation of the bond by the surety the manufacturer license is automatically deemed canceled.
