New and used travel trailers for sale are listed on many websites, including RV Trader, Camping World and RV Online. Websites such as Salvage Bid and eBay allow users to bid on used travel trailers up for auction.
As of 2015, the RV Trader and Camping World websites offer users interactive tools to search for used travel trailers by manufacturer, model, year and distance from specific zip codes. RV Trader provides advanced search tools to narrow results based on price, condition, mileage and even color. RV Online lists all travel trailers for sale in one section, and users are able to sort results by size, price and location.
On eBay's website, users can refine the search results by selecting options in categories such as length, mileage, model year, sleeping capacity and condition. Users can place bids on the travel trailers and in some cases, buy them instantly. The Salvage Bid website allows users to participate in live auctions as they occur, as well as place bids on ongoing online auctions. Travel trailers and RVs found on the site have some level of damage and require repair by the purchaser. The damage type and location is specified on each listing, with descriptions such as "interior burn," or "hail; right side."
