What's the best way to find out the value of your RV? We have used 'nada.com' - yet the used RV pricing they give you is for 'Retail' - which I believe is probably higher than you can really get for your RV. Would this be a true statement and/or good assumption? And it doesn't appear you can get a used value for an RV on Kelly Blue Book, 'kbb.com'. Are there any other online sites where you can get a used value for your RV - to help price an RV you want to sell. Any thoughts would be appreciated. Thanks..
