You'll most likely see Doug or his son Wayne when you pull in after a few weeks out. It’s not only comforting, it feels damn fine. Shaking the hand of the owner and knowing Doug’s and the DSW team got your back is a very fine thing.

Wayne & Doug Prall


The trucking business is a part of Doug Prall’s DNA. His dad, George Prall, started a piggyback hauling company for the Santa Fe railroad in 1960, in Blythe, California.

George opened Drivers Dispatch in Phoenix in 1969, seeing the opportunity of providing private carrier drivers in a highly-regulated environment. Once the industry deregulated, George opened Highway Express. It was about 1980.

George was hauling freight between Chicago and Nogales, AZ. Then, when Doug was around 15, he moved to Phoenix. Drivers were like family, in and out daily, and Doug drove his first rig (underage), hauling Pennzoil from LA to Phoenix.

Doug took over the driver staffing and trucks in 1989, forming a partnership with Don Digby Senior, and Digby Southwest (DSW) was born.

In 1995, Doug became the sole owner of DSW. And in 1996, Doug and Jerry Moyes worked up an agreement for the DSW fleet to haul Swift’s freight. Since then, Doug and his family has grown a suite of industry related companies, including 4 distinguished driver’s training schools (in Tucson, Phoenix, Yuma and on the Ft. Bliss post in El Paso), and a DOT regulation consulting division and a commercial vehicle maintenance and repair shop.

Wayne Prall earned his way back into the main office. After graduating from University of Arizona, Wayne worked with Edward Jones as a financial advisor for eighteen months. He then went through the Phoenix Truck Driving School and drove over-the-road for Swift for 9 months. He then worked in the office with Navajo to handle multiple office positions when the opportunity to work as Traffic Supervisor for Albertson Distribution came up, where he worked for 2-1/2 years. Wayne started back with DSW in January of 2017.
