How do I find the value of my RV before selling?

The most reliable RV valuation sources are the NADA RV Guide (nadaguides.com) and J.D. Power RV Valuations. Enter the year, make, model, and length for a baseline value range. Then check current asking prices on RV Trader and Facebook Marketplace for comparable units within 200 miles. Condition, mileage (for motorhomes), upgrades, and storage history adjust the value significantly. A dealer can give you a quick appraisal, though their buy number will be lower than private-sale value.
