Shannon Johnson is the founder of Used Big Rigs.com. He has been in the trucking industry for several years, and has an in-depth knowledge of what it takes to sell, and buy, big rig vehicles. Used Big Rigs. Com is in the business to help freight transportation companies and owner-operators with affordable advertising for used trucks, and easily connecting them with buyers that know they can rely on us with up-to-date information. We know that by connecting buyers and sellers, we are building relationships that will last a lifetime, based on honesty, trust and quality products. Our goal is to build the largest used big rig inventory available online. We realize that most owner-operators have schedules that keep them on the road for weeks at a time, and with our user-friendly format, we are hoping to make things as easy as possible for our customers. We realize that time is money, especially when you are completely in charge of maintaining, operating and updating your truck. Owning a reliable vehicle is crucial to your success as a driver, and we want to make it as easy as possible to search and update information for you without taking away the wages that come from being off the road.
