1. A person shall not engage in this state in the business of selling at retail new towable recreational vehicles of any line-make, or represent or advertise that the person is engaged in or intends to engage in such business in this state, unless the person is authorized by a manufacturer-dealer agreement between that person and the manufacturer or distributor of that line-make of new towable recreational vehicles to sell the vehicles in this state, and unless the department has issued to the person a license as a towable recreational vehicle dealer for the same line-make of towable recreational vehicle which the dealer is authorized to sell under the manufacturer-dealer agreement.
 2. A person, other than a licensed dealer in new towable recreational vehicles, shall not engage in the business of selling at retail used towable recreational vehicles or represent or advertise that the person is engaged in or intends to engage in such business in this state unless the department has issued to the person a license as a used towable recreational vehicle dealer.
 3. A person is not required to obtain a license as a dealer if the person is disposing of a towable recreational vehicle acquired or repossessed, so long as the person is exercising a power or right granted by a lien, title-retention instrument, or security agreement given as security for a loan or a purchase money obligation.

 6. A dealer shall not make and enter into a security agreement or other contract unless the agreement or contract meets the following requirements:

 a. The security agreement or contract is in writing, is signed by both the buyer and the seller, and is complete as to all essential provisions prior to the signing of the agreement or contract by the buyer except that, if delivery of the towable recreational vehicle is not made at the time of the execution of the agreement or contract, the identifying numbers of the towable recreational vehicle or similar information and the due date of the first installment may be inserted in the agreement or contract after its execution.
 b. The agreement or contract complies with the Iowa consumer credit code, chapter 537, where applicable.
