Built to Perform: How Summit Service Trucks Improve Fleet Performance
See how Ascendum Machinery supports over 100 field technicians with Summit service trucks powered by Miller® EnPak® — improving uptime, lowering operating costs, and delivering reliable performance on every jobsite.
About Ascendum Machinery
Ascendum Machinery is one of the largest heavy equipment dealers in the Southeast, serving customers across Georgia, North Carolina, South Carolina, and Tennessee. With 12 branch locations and a fleet of more than 100 field technicians, their team supports a wide range of equipment brands, including Volvo CE, Sennebogen, Sandvik, LeeBoy, Bobcat, and Gradall.
Ascendum’s customers expect fast response times and reliable uptime. They also expect technicians to finish repairs on the first visit. To meet those expectations, Ascendum relies on service trucks built for demanding field work. These trucks must deliver durability, safety, and long-term performance.
The Challenge: A Fleet Built for Uptime, Safety, and Productivity
Ascendum supports customers who depend on fast service and reliable uptime. Their technicians cover large territories and face demanding work conditions. Each visit must be efficient, safe, and completed with the right tools.
Ascendum needs trucks that handle heavy equipment, long service hours, and operate in tough environments. The fleet must stay consistent across all branches to simplify training and support. Reliable builds also help retain skilled technicians, which remains a key priority.
Good technicians are hard to find, and these trucks help us keep the ones we have.”
— Patrick Overstreet, Director of Product Support, Ascendum Machinery
The Summit Solution
Ascendum and Summit have worked together for more than a decade, refining the service truck design based on technician feedback and real-world performance. Each Summit build delivers:
Summit has partnered with Ascendum for more than ten years. Each truck design reflects technician feedback and real field needs. This helps Ascendum keep its fleet consistent, reliable, and easy to support across all branches.
Summit builds each truck as a complete system. The body, crane, drawer packs, controls, and integrated power equipment all work together. This includes the EnPak® A60GBHW system, which fits cleanly into Summit’s layout and workflow. The goal is simple: give technicians a truck that supports safe, efficient work every day.
Summit also refines each build across the fleet cycle. Minor updates improve storage, access, labeling, and overall usability. These improvements help technicians stay productive and reduce the time needed to learn new trucks.
“Summit invited us into the plant to walk through their process and help refine the truck spec based on what mattered to us. The core spec has stayed consistent for over a decade, but they’ve worked with us to evolve it as our needs changed.”
— Patrick Overstreet, Director of Product Support, Ascendum Machinery
Designed to Keep the Best on Your Team
In today’s labor market, retaining experienced technicians is just as important as recruiting them. Ascendum understands that the right service truck plays a significant role in keeping technicians satisfied, confident, and equipped to succeed — and Summit’s design approach supports that goal.
Summit-built service trucks help Ascendum reinforce a people-first strategy, giving technicians tools and equipment that reflect the company’s commitment to their safety and success. Every component — from the body construction to the crane, drawer systems, and ground-level controls — is intentionally designed to make the technician’s day easier, safer, and more efficient.
A well-designed truck reduces daily frustrations, prevents unnecessary strain, and gives technicians the professional image they want when they show up on a jobsite. When techs can trust their service trucks, focus on repairs rather than workarounds, and take pride in their equipment, it becomes a direct contributor to higher morale and lower turnover.
“The easiest way to measure success is to listen to your technicians. These trucks prove we’re listening.”
— Jeff Wilbanks, Product Support Manager“We want our employees to expect more out of us. That means reliable trucks, fewer headaches, and equipment that works when they show up.”
—Patrick Overstreet, Director of Product Support, Ascendum Machinery
First Impressions Matter on the Jobsite
Every service call is an opportunity to reinforce Ascendum’s professionalism. When a technician arrives in a Summit-built service truck, the experience customers have before a single tool is lifted already sets the tone for the job ahead.
Summit trucks are built to help technicians show up prepared, with organized storage, reliable power, and a layout that allows them to complete more repairs in a single visit. This level of readiness translates to stronger customer confidence — a technician who arrives with the right equipment signals capability, credibility, and efficiency.
For Ascendum, the difference is clear: a well-equipped technician in a Summit truck paired with Miller EnPak power systems delivers a noticeably stronger first impression than competitors with smaller bodies or limited equipment. When Ascendum techs roll onto a jobsite, customers see a vehicle designed for serious work and a company invested in doing the job right.
“Rolling onto the jobsite in a Summit truck with the EnPak shows we’re there to do business and get the job done. If someone rolls up in a smaller truck with a little compressor, they might have to come back. I don’t.”

Reliable Support and Long-Term Fleet Stability
Ascendum’s fleet depends on service trucks that deliver consistent performance over many years and multiple build cycles. Summit’s relationship-driven approach ensures every truck is engineered not only for the first day on the job, but for the long haul — with durability, serviceability, and repeatability built into every component.
Summit’s support model gives Ascendum a single, trusted partner for body, crane, drawer systems, and electronics. If a technician needs help, Ascendum knows exactly who to call — no need to chase multiple vendors or piece together answers. This streamlined support keeps trucks in the field and reduces downtime.
Over time, Summit’s ongoing refinements mean each new truck in Ascendum’s replacement cycle is more efficient, more reliable, and more tailored to technician needs than the one before it—the result: a smoother fleet transition, consistent builds across all branches, and long-term equipment value.
“We don’t have bed life issues. No crane issues. No drawer failures. When we’re ready to replace a unit, Summit is already there with a better solution than the last.”
— Patrick Overstreet, Director of Product Support, Ascendum Machinery
Integrated Partner: Miller® EnPak® Power Systems
To support Ascendum’s demanding field service environment, Summit integrates Miller EnPak® A60GBHW all-in-one power systems into its standardized fleet specification. This integration gives technicians the reliable, engine-off power they need for welding, air, battery charging, and 120V AC tools — all in a compact package that reduces idle time, noise, and emissions.
EnPak complements Summit’s build philosophy: engineered efficiency, technician-focused design, and dependable jobsite performance. The result is a cleaner, quieter, and more productive service truck that keeps technicians moving from one job to the next without unnecessary strain on the chassis.
Measured Results from EnPak Integration
Between the quality of Miller® equipment and ongoing support, Ascendum has strengthened its commitment to reliable field service for its customers.
Since integrating EnPak® units across its fleet, Ascendum has experienced measurable operational and financial benefits, including:
- Fuel savings of 1 to 1.5 MPG
- An anticipated return on investment in under two years
- Extended chassis life
- Lower maintenance costs
- Fewer emissions-related repairs due to reduced idle time
These performance gains, combined with positive technician feedback, led Ascendum to standardize EnPak® units across its fleet of more than 100 service trucks. Today, E®nPak units are considered standard equipment on all new trucks entering the fleet. Learn more about the EnPak® A60GBHW
“With EnPak, we’re quieter, cleaner, and more productive. It’s a smarter way to work.”
