Sites such as Truck Paper and Trailer Shopper deal extensively in used and new heavy equipment such as tow trailers while online auction sites like eBay offer extensive catalogs of listed items, including used trailers. These sites give buyers a range of prices and models from which to choose, enabling them to make informed purchases.
Truck Paper is a private listing site where sellers can post trucks and equipment such as trailers for sale. Items are listed with descriptions of their make, model and condition along with pricing. They can be sorted and searched by geographical location and also by price or price range.
Trailer Shopper deals specifically in trailers of all kinds. It has options to place ads as well as a utility that allows buyers to find dealers in their areas if they wish to make a purchase. It also has a list of frequently asked questions for new buyers and those interested in the mechanics of the site and of trailer operation.
eBay is an online auction site where sellers can post items such as used trailers for bid. Bidders then compete to purchase the item, and if competition is low, a trailer could potentially be had at a lower price than it would usually command.
