Dale Dorris

 Founder, Owner, and Master Mechanic

Dale Dorris is the Founder, Owner, and Mechanic of Dale’s APU Sales, a company dedicated to helping owner-operators, independent drivers, and fleet managers maximize the performance and reliability of their auxiliary power units (APUs). With a focus on refurbished APUs, repairs, diagnostics, installations, and ongoing support, Dale has built the business around providing practical solutions that keep trucks on the road while helping customers reduce unnecessary downtime.

At Dale’s APU Sales, Dale works with customers across the trucking industry, offering services that range from refurbished APU sales to emergency repairs and complete system installations. Whether assisting a single owner-operator or supporting an entire fleet, his goal is to provide dependable equipment and knowledgeable service that meets the demands of everyday trucking. 

A Career Focused on Refurbished APUs

Refurbished auxiliary power units are at the center of Dale’s work. Through Dale’s APU Sales, he specializes in helping customers find cost-effective APU solutions that deliver dependable performance without the expense of purchasing new equipment.

The company offers professionally refurbished APUs backed by a one-year parts-and-labor warranty, giving drivers confidence in the equipment they install on their trucks. Every system is intended to help drivers stay comfortable during rest periods while reducing unnecessary engine idling and supporting more efficient truck operation. Dale’s commitment to refurbished APUs reflects his belief that quality equipment, careful inspection, and proper service can provide lasting value for customers throughout the trucking industry. 

Supporting Drivers and Fleets Every Day

Dale’s current work centers on serving everyone within the trucking industry. From independent owner-operators to commercial fleet managers, he understands that dependable equipment is essential to keeping schedules on track.

Beyond selling refurbished APUs, Dale’s APU Sales provides installation, diagnostics, repair, and replacement services for multiple APU brands, including Thermo King, Carrier, and Green APU systems. The company also performs DPF cleaning, aftertreatment repairs, emissions diagnostics, and emergency APU repairs to help customers resolve issues quickly when unexpected problems arise. 

Recognizing that breakdowns do not always happen during convenient hours, Dale has built his business around responsive service designed to minimize downtime whenever possible. Same-day repairs and installations, along with emergency repair services, reflect the company’s commitment to helping customers return to the road as efficiently as possible. 

Helping Customers Make Practical Decisions

One of Dale’s priorities is helping customers understand the options available for their trucks rather than simply selling equipment. Every operation has different needs, and choosing between repairing an existing APU, replacing components, or investing in a refurbished unit requires practical knowledge of the equipment and its condition.

By offering diagnostics alongside repairs and refurbished unit sales, Dale helps customers evaluate solutions based on their specific circumstances. Financing options for refurbished APUs further expand accessibility for drivers who need dependable equipment while managing operating costs. 

This practical, customer-focused approach allows truck owners to make informed decisions that support both immediate operational needs and long-term equipment performance.

Committed to Reliable Service

The trucking industry depends on reliable equipment, and Dale’s work reflects that reality. Every repair, installation, and refurbished unit represents an opportunity to help customers avoid unnecessary downtime and maintain productivity.

The Dale’s APU Sales team includes ASE-certified technicians with more than 20 years of industry experience, allowing customers to receive service from professionals familiar with a wide variety of APU systems and related components. That experience supports the company’s ability to diagnose problems accurately, perform quality repairs, and install equipment correctly for dependable long-term operation. 

Quality service extends beyond technical repairs. Dale also emphasizes customer support by working with drivers throughout the repair or purchasing process, helping them understand available solutions and what to expect from the work being performed.

Serving the Trucking Industry Nationwide

Although Dale’s APU Sales operates from locations in Springfield, Missouri, and Lonoke, Arkansas, the company serves customers throughout the trucking industry across the country. This broad service approach allows drivers and fleet operators to access refurbished APUs, repair services, diagnostics, and installations from a business focused specifically on auxiliary power systems. 

Because commercial trucking operates in demanding conditions, equipment must perform consistently across long distances and varying climates. Dale understands these challenges and has structured his business around providing solutions that support reliability, driver comfort, and operational efficiency.

His work continues to focus on meeting the everyday needs of truck owners by delivering practical service backed by industry knowledge and experience.

A Business Built Around the Needs of Drivers

Throughout his work at Dale’s APU Sales, Dale remains focused on one objective: helping customers keep their trucks operating efficiently with dependable APU solutions.

From refurbished unit sales and professional installations to emergency repairs and system diagnostics, every service is designed to support drivers who rely on their equipment every day. By working with customers across the trucking industry and concentrating on refurbished APUs, Dale has established a business centered on practical service, knowledgeable support, and long-term value.

Whether someone needs a replacement APU, expert diagnostics, routine repairs, or assistance selecting the right refurbished system, Dale strives to provide solutions that fit each customer’s operational needs while helping them stay on the road with confidence.
