You can find used refrigerated trucks for sale by looking on specialized trucking classifieds sites, such as CoomercialTruckTrader.com and TruckPaper.com, as well as on general classifieds sites, such as Craigslist. Auction sites, such as eBay, also commonly feature listings for used refrigerated trucks.
CommercialTruckTrader.com gives you the ability to filter listings for used refrigerated trucks by several factors, including manufacturer, purchase option, truck class, fuel type and price range, as of March 2015. Each listing on the site contains details about the available options for the truck and a description of its current condition. Listings can also contain pictures and videos of the truck, though there are no requirements for sellers to do so. If you see a truck you are interested in purchasing, contact the seller using the site's built-in messaging system or by contacting the seller directly via any included means, such as a phone number.
While Craigslist gives sellers the ability to include text and pictures in listings, it also does not place any minimum requirements on what type of content to include. As such, you may need to contact the seller to request additional information or arrange an in-person visit to the truck. Always exercise caution when meeting a seller from Craigslist and avoid meeting at night or alone.
