SUMMIT COUNTY, UT — Three Rokbak RA30 Articulated Dump Trucks (ADTs) are helping Mark 25 Homes navigate excavation on the scenic slopes and rugged terrain of Summit County, Utah.
Supplied by Rokbak dealer Rasmussen Equipment, based in West Valley City, Utah, the RA30s perform critical daily hauling operations for the excavation phase of a multi-year project that will see the creation of 133 single-family homes and 48 cottages in Park City’s Black Rock Estates development.
Mark 25 Homes, a home builder since 2012, has partnered with Rasmussen Equipment for many years.
The three Rokbak RA30s arrived on site in late June 2025 and began hauling immediately. Working five days a week across a sprawling job site that spans steep slopes and variable terrain, the RA30s are integral to managing the common excavation work that underpins the early phases of construction. The project is divided into multiple stages and is expected to maintain its fast pace for several years.
As construction continues, the RA30s will move thousands of cubic yards of material each week.

“Every day counts on a job like this,” said Jarrett Lindgren, Superintendent for Mark 25 Homes. “The RA30s give our operators a real sense of control thanks to the engine exhaust brake and transmission retarder. These features make all the difference on our mountain site. They boost safety, speed up cycles, and keep our drivers comfortable and confident.”
The RA30 delivers 30.9 tons of payload, with a fuel-efficient engine and automatic traction control. On the steep gradients of the Black Rock Estates site, the RA30s maintain grip and stability in loose or muddy conditions.
Mark 25 Homes Lead Technician Les Brewer said he has been impressed with the ease of maintenance and reliability the RA30s offer, especially under the full support of Rasmussen Equipment’s warranty package.
“With the RA30s on site and Rasmussen behind us, I’ve been able to focus on maintaining the rest of our fleet,” he said. “It’s a major relief knowing we have that kind of support, and the downtime is kept to an absolute minimum.”

Rasmussen Equipment has been the official Rokbak dealer for Utah since 2015.
“At Rasmussen Equipment, we know that uptime is everything for our customers,” said Mark Balanzich, Service Manager. “That’s why our team is committed to providing fast, knowledgeable aftersales support to help keep Rokbak trucks working hard and performing at their best. With our long-time relationship with Rokbak, we’ve built a strong united front based on trust, reliability, and a shared dedication to customer success.”
“Rasmussen is more than a dealer; they’re a partner," Lindgren added. "Whether it’s prompt delivery, parts availability, or ongoing service, they always come through.”
To further enhance the performance of their new RA30 fleet, Mark 25 Homes is using Rokbak’s Haul Track telematics system, which provides real-time data on machine location, operating hours, fuel consumption, and fault codes.

“With Haul Track, we’re not just moving dirt, we’re moving forward with smarter, more informed decisions,” Brewer said.
With consistent uptime levels, the RA30 trucks' fuel consumption averages 4 to 5 gallons per hour. By lowering the overall cost per unit of material moved, Mark 25 Homes can keep its development timelines on track and budgets under control.
“The Rokbak RA30 is built to move more for less,” said Greg Gerbus, Rokbak Regional Sales Manager - North America. “And in Utah’s demanding conditions, that reliability is more than a spec, it’s a necessity.”
