Buying a used camper from a private seller can save a buyer money because one can often negotiate on the price. Private sellers also typically have more information about the campers and are likely to know the complete maintenance histories of the vehicles.
Buying a used camper from a private seller means dealing directly with the owner of the RV, who may know more about the history of the vehicle than a dealer. Campers have many more parts to maintain and repair than cars, so working with someone who knows the unit inside and out is a significant bonus.
The Internet offers hundreds of used campers for sale by private sellers all over the country. Many prospective buyers can also find campers for sale in neighborhood driveways or while traveling.
