These people prey on people. They search ads. Find your telephone numbers and offer an advertisement ad for your boat, home, or rv. You do not need to find out the market value of your item. You can go to NADA.com to research and RV. The service is non-refundable. I would never recommend their service to anyone. They hound you. I gave in and paid a heft fee of $299 for a service that did not produce. Do not use them. Beware. They have fast tongues.
