Typically when a customer buys a new Roadtrek they do not have a trade-in, or if they do, they have a friend or relative that buys their old unit. Once in a while, we do get Roadtreks in trade and they are offered to prospective customers on our waiting list. If you are interested in a used unit, call us at 800 601-6960 and leave us your contact information. When a used unit becomes available, we will contact you.
