About Johnson Companies

The Johnson family of companies represents third generation family ownership of three closely integrated companies: Johnson & Towers, Johnson Truck Center and Dovell & Williams. Our business history dates back to 1926 when we started providing parts and service to the marine industry. Over the years our footprint has enlarged dramatically in a wide range of markets in the Mid-Atlantic region. Our territory (depending on the company and product) includes Southern New Jersey, Maryland, the lower Eastern Shore of Delaware, Washington D.C., and the bordering counties in Northern Virginia.

Under the Johnson & Towers umbrella, we are an authorized distributor for products and parts manufactured, sold and warranted by Detroit Diesel, Allison Transmission, MTU and Volvo Penta. We are able to provide the end-uses of those leading brands with premier service, up-to-date technical support and genuine parts to service the marine, standby generator, on highway (with a special emphasis on coach and transit) and off highway (construction and industrial) markets. We are part of the nationwide WheelTime network of associated distributors with considerable purchasing power and a wide range of service locations including our own 3 distributor stores.

We operate traditional truck dealerships under the banner of Johnson Truck Center and Dovell & Williams – representing OEMs with the leading market share in their class: Freightliner, Western Star, Autocar, Isuzu and Fuso. Our Used Equipment department can help you find the specific vehicle that meets your needs. Our growing Fleet Maintenance division supports all 7 locations at our 3 companies and can design any type of customized PM or Fleet Management program to keep your trucks available for your transportation needs.

We look forward to providing you with the products and services that set us apart as one of the premier providers in the industries we serve.
