The National Automobile Dealers Association's RV appraisal guide assesses the wholesale, retail and suggested list prices of used RVs using information such as the mileage and optional equipment. The NADA provides print editions as well as an easy-to-use online version and updates both multiple times per year.
The guide provides information for truck campers, camping trailers, motor homes, travel trailers, fifth wheels, park models and heavy-duty tow vehicles. The 2015 print version contains pricing information for the years 2001 to 2015, while the 2015 update of the online version contains pricing from 1966 to 2015. In addition to the RV guide, NADA also provides guidebooks on a wide range of other vehicles, including classic and exotic cars, motorcycles, ATVs and marine craft.
