David A. Thompson founded TEC Equipment in 1976. During those early days in Portland, Oregon, TEC Equipment was known as Thompson Equipment Company and its business was buying and selling used trucks and trailers.

Today, David is joined by his three sons, David O., Chris, and William. This proud, family-owned business is now one of the largest full service truck and trailer dealerships in the United States. We have 30+ locations in Washington, Oregon, Nevada, California, Arizona, Nebraska, Iowa and South Dakota, serving a population base of more than 40 million people.

TEC Equipment’s growth in the dealership industry is unprecedented. Our expansion from a single used truck center in Portland, Oregon to 30+ truck and trailer dealerships in over 20 cities across Washington, Oregon, Nevada, California, Arizona, Nebraska, Iowa and South Dakota is a tribute to this. Our focused strategy has yielded over 40 years of market share growth and financial stability.

TEC Equipment has focused its growth strategy along the Interstate 5 corridor. It is the route many of our original customers traveled and on which they continue to operate today. Covering more than 2,000 miles of I-5, TEC Equipment is the only dealership group to offer this footprint, providing seamless service, reliable pricing, discounted fuel, and extended hours. In addition to new and used truck and trailer sales, parts, and service, our dealerships provide truck leasing and rental, financing, insurance, and auto transport equipment sales and service.
