Quality Used Truck Sales

Our job is to make finding your truck easy and painless. If we don’t have what you’re looking for, don’t worry – we’ll find it. Our salesmen have a wealth of connections to track down the truck, trailer or piece of equipment you’re looking for. When you buy from us, you get the added bonus of quality. Because we are a Cummins and International dealership, all used vehicles must pass a state quality inspection as well as a US DOT inspection. We can also provide a warranty for up to 2 years and 250,000 miles. If you’re looking for one truck, or want to upgrade your commercial truck fleet, we offer financing to make your purchase easier on your budget.
