The trucking people's people
Serving the NW trucking community since 1945

For the past 67 years DSU Peterbilt & GMC Inc has been proud to serve the trucking community of the Pacific Northwest. Since 1945 we have worked to “Treat every customer as if we were the customer.” This philosophy hasn’t changed and is evident in the long term relationships we hold with our customers; they are part of our ‘family’. Over the past 67 years DSU has grown from a tarp strung up behind a furniture store in North Portland, to a 4 location full sales, service, parts, and leasing company serving the Pacific Northwest from Southern Washington to Northern California. However, we haven’t lost that small, hometown feel. Many of our employees have been with the company for decades, helping it grow by exceeding customer expectations.   DSU was ranked the #1 GMC dealer in Oregon for 2011! DSU is one of those “best kept secret” types of dealer who pride ourselves on helping customers find the best solution for their need, and earning your business for a lifetime rather than making a quick sale. Give us a try. You will be pleasantly surprised!
