Every day, thousands of commercial vehicles pull into the Iowa 80 Truckstop in Walcott, Iowa. Drivers fuel their trucks, grab a meal, take a shower, and head back onto Interstate 80. Just beyond the parking lot sits a museum dedicated to the industry’s history, yet many visitors never walk through its doors.

That isn’t unusual. Unlike aviation or railroading, trucking was built around equipment that worked until it wore out. Trucks weren’t set aside for future generations. They were rebuilt, traded, cannibalized for parts or eventually scrapped, leaving relatively few examples behind. The museums that exist today were created because collectors, manufacturers, and industry organizations recognized that much of trucking’s history could disappear if no one preserved it.

If your travels put you nearby, these are some of the destinations worth making time for.

Iowa 80 Trucking Museum, Walcott, Iowa

The Iowa 80 Trucking Museum feels like a natural extension of the truck stop next door. Many visitors arrive expecting a handful of restored trucks and quickly realize the collection tells a much bigger story.

Walking through the galleries, it’s easy to see how rapidly commercial vehicles changed during the twentieth century. Early trucks look more like oversized wagons than modern tractors, with exposed mechanical components, narrow tires and cabs that offered little protection from the weather. Move forward a few decades and familiar design elements begin to appear as manufacturers responded to longer routes, heavier freight and growing interstate commerce.

The museum doesn’t rely on technology or interactive displays to explain those changes. The trucks do that on their own. Looking at a restored 1910s work truck beside equipment built several decades later makes it clear how quickly the industry evolved as America’s freight network expanded.

Its location is another reason the museum stands apart. Few trucking museums sit beside one of the busiest truck stops in North America, making this one an easy visit for drivers already traveling Interstate 80.

Mack Trucks Historical Museum, Allentown, Pennsylvania

Ask a group of truck drivers to name an American truck manufacturer, and Mack will almost always be part of the conversation.

The Mack Trucks Historical Museum reflects that legacy, but it isn’t built around rows of polished tractors alone. Historic vehicles share space with factory records, engineering drawings, advertising artwork, and production documents that reveal how the company developed many of its best-known models.

Those archives provide something most transportation museums cannot. They connect the finished truck with the decisions made long before it reached the highway. A visitor can trace the evolution of Mack’s engineering, see how designs changed over time, and better understand why certain models became industry standards.

Because access is limited during parts of the year, checking current visitor information before making the trip is recommended.

The Highway That Helped Shape Long Distance Trucking

Route 66 is often remembered for classic cars, roadside diners and family vacations, but commercial transportation played an important role in its history as well.

Before Interstate 40 became the primary east-west corridor through Oklahoma, trucks moved freight through towns that depended on highway traffic for their economy. Fuel stations, repair shops, restaurants, and small businesses grew because commercial drivers and travelers passed through every day.

The Oklahoma Route 66 Museum in Clinton captures that period without trying to romanticize it. Exhibits explain how communities developed around the highway and how dramatically those communities changed after interstate construction redirected traffic onto faster routes.

For drivers crossing western Oklahoma today, it’s a reminder that many of the roads now considered secondary once carried the same long-distance traffic that fills the interstates.

Preserving More Than Old Trucks

The trucks inside these museums are impressive, but they’re only part of what has been preserved.

Original photographs document fleets that disappeared decades ago. Engineering drawings record designs that shaped future generations of commercial vehicles. Highway exhibits explain why freight moved where it did, while restored signs, tools and equipment capture details that rarely survive once a business closes or a fleet is replaced.

Taken together, those collections tell a story that extends beyond individual trucks. They show how manufacturers responded to changing freight demands, how highways reshaped the movement of goods across the country and how an industry built around constant motion still found ways to preserve pieces of its past.

The next time you find yourself parked at Iowa 80, traveling through eastern Pennsylvania or crossing Oklahoma on Interstate 40, one of trucking’s most interesting stops may be much closer than you expected.

Bringing a Classic Back to Life

The 1984 Mack R Model, originally custom-built for Johnny Prescott and Son Oil in Concord, New Hampshire, holds a special place in Mack’s legacy. For Grayce, restoring it was more than just a challenge; it was a personal mission.

“I’ve always preferred older trucks over new, and to me, there is nothing cooler than an old dog that looks new,” said Emmick. “Growing up around Mack trucks made it easy to fall in love with the brand. The first Mack I sat behind the wheel of is a 1985 R Model that has been on our farm since 1992.”

The year-long restoration project showcased a delicate balance of preserving history while incorporating subtle modern updates. The truck still boasts its original steering wheel cap, engraved with “Custom Built for Johnny Prescott Oil Co.,” and vintage Mack bulldog mirror ornaments featuring their distinctive long ears and tails. It’s a stunning example of how tradition can meet innovation.

An Icon in the World of Trucking

Doug Maney, curator of the Mack Trucks Historical Museum, hailed the significance of this restoration effort.

“The Mack R Model series is iconic in trucking history, creating the benchmark for American transportation from 1965 and maintaining it through the mid-2000s,” Maney explained. “The fact that our trucks are not just dependable tools is reinforced by the R model, generating a source of pride for their owners. Grayce’s influence and hands-on effort, preserving original details while thoughtfully modernizing others, helps us tell the story of Mack’s heritage and the evolution of trucking in America.”

Powered by Passion and Community

The restoration was made possible by the enthusiastic support of Mack fans and the trucking community. Jim Rymes of J & H Rymes and Daughters in Lakewood Ranch, Florida, donated the truck used as the base of the project. Gregg Hoffman with Underdog Transport in Bangor, Pennsylvania, volunteered to haul the truck to Grayce’s farm in Kentucky for the restoration.

“Mack fans are loyal, dedicated, and supportive,” said Maney. “The Mack brand roots itself into people just as it has American and world history.”

It didn’t stop there. Grayce’s partner, Gavin Spoor, also contributed to the project by donating a fifth wheel from his own truck, a vehicle that played a pivotal role in their relationship during a memorable 10-hour drive from Texas.

“Mack Trucks has been an integral part of my story, and being able to donate to their legacy is nothing short of empowering to me,” Grayce reflected.

Preserving History for Future Generations

The restored Mack R Model isn’t just a truck; it’s a testament to the fusion of craftsmanship and passion, bridging generational gaps in the trucking industry.

“We’re honored to welcome this historic R Model into our collection,” said Maney. “What makes this donation particularly special is how it bridges generations, combining the craftsmanship of Mack’s past with the passion of a young enthusiast who understands the importance of preserving our trucking heritage. It will serve as an inspiring example to museum visitors of Mack’s enduring quality and the continuing legacy of our favorite brand.”

A Restoration Journey Captured on Video

The restoration process unfolded publicly through a YouTube series, allowing viewers to follow Grayce’s meticulous work step by step. Through triumphs and challenges, the series emphasized the importance of learning by doing, a value Grayce holds close to her heart.

“Through the restoration series and seeing the end result in the museum, I hope visitors and viewers can appreciate the learning process,” she explained. “Nobody wants to learn the hard way, but sometimes that’s necessary to understand your limits, what you need to improve on, and how you can do better.”

A Farm with a Rich History

Grayce’s restoration work is deeply rooted in her personal history. As part of the eighth generation to run Emmick Farms, established in 1813 along the Ohio River in Lewisport, Kentucky, she carries on a legacy that spans more than two centuries. The farm, known for its corn, soybeans, and winter wheat, is steeped in history. Its riverbank was once home to Abraham Lincoln’s ferry business, where Abraham Lincoln won his first court case, forever shaping his political career.

Mack Trucks Historical Museum

The restored 1984 Mack R Model now proudly resides in the Mack Trucks Historical Museum, located within the Mack Experience Center in Allentown, Pennsylvania. This nonprofit museum celebrates its 40-year history of preserving and showcasing Mack’s invaluable contributions to American industry.

The 15,000-square-foot facility houses an impressive collection of 30 operational vintage vehicles, alongside archives that hold over 40 million pages of documents detailing Mack’s role in pivotal moments, from World War I to iconic infrastructure projects such as the Hoover Dam and the New York City subway system.

Visitors to the museum can now view Grayce’s remarkable restoration effort in person, joining the museum’s lineup of historical artifacts that tell the story of Mack’s dedication to excellence and innovation.
