Older motorhomes, are worth what you can buy/sell them for. As a buyer I want to buy for NADA low book, as a seller I want to sell it for all I can get. Some where in between is a happy medium. With that said generally no financing is available on older coaches buyers will usually be a whole lot tighter with thier cash which = lower sales prices. The NADA, Kelly BB, are good guides but they are guides and the value of older coaches depends greatly on condition. Generally you will also do better at the dealers for older coaches than you will in someones yard, because the dealer is not personally attached to the coach, beleave me they do not have any more real money over NADA dealer wholesale in any used coach on thier lot. If they do they won't be around for long.
