The directions on my phone seemed wrong.
I was winding through one of New Jersey’s quietest suburbs, past manicured lawns and country clubs, when I spotted it. A massive gun barrel, the kind that belongs on a battleship, sitting casually on a hillside like someone’s eccentric lawn ornament. Two-hundred-and-fifty-thousand pounds of naval artillery. In Basking Ridge.
I knew then that I was in the right place.
What I didn’t know was that I was about to step into what can only be described as a time machine disguised as a truck museum. Or maybe it’s a truck museum disguised as someone’s magnificent obsession. Either way, the Mahan Collection isn’t just a nonprofit museum, it’s proof that one person’s love affair with a 1927 truck can evolve into one of the most remarkable collections in the world.
It Started With a Wedding (and a Very Understanding Bride)
Imagine it’s your wedding day, and instead of a limousine or a horse-drawn carriage, your groom pulls up in a five-ton antique truck. That’s what happened when Gary Mahan married Elizabeth, riding off into their future in a 1927 AC 5 Ton truck he’d restored himself.
Elizabeth would later joke that she wasn’t sure if she was marrying Gary or the truck.
Spoiler alert: she married both.
That “Wedding Truck” was just the beginning. Fast forward to today, and that single truck has multiplied into nearly 200 antique trucks spanning 85 years of American history, all meticulously restored and displayed across 40 acres and six buildings. It’s the kind of collection that makes you wonder: at what point does a hobby become a calling?
The First Building Is Just the Appetizer
When you walk into the first warehouse, you think you’ve seen it all. Rows of gleaming Mack trucks from the 1920s and 30s, their chrome catching the light, their paint jobs so perfect you’d swear they just rolled off the assembly line. Vintage signs advertising long-gone trucking companies line the walls. Old gas pumps stand at attention like soldiers from another era.
You take your photos. You read the placards. You think, “Wow, this is really something.”
Then someone mentions there are five more buildings. The buildings and outdoor exhibits are over 40 acres – but don’t worry, they have golf carts you can use to get around!
Around Every Corner, Another Era Waiting
Here’s what nobody tells you about the Mahan Collection: it’s impossible to prepare for. Every time you think you’ve grasped the scope of it, you turn a corner and there’s another building, another century, another story unfolding.
In one building, trucks sit exactly as they were found—rusted, weathered, still caked with the dirt from whatever field they were rescued from. In another, you’ll find construction equipment so massive it seems impossible it could fit through the doors. There are trucks that hauled coal during the Depression, trucks that served in wars, trucks that built America’s highways.
And then there’s the stuff. Oh, the glorious stuff. Vintage toys, old photographs, trucking memorabilia that would make a collector weep. Every inch of wall space tells a story. You could visit ten times and still discover something new.
But Here’s the Thing That Gets You
What makes the Mahan Collection truly special isn’t just the trucks—it’s the passion bleeding through every rivet and bolt. A small crew of four full-time restoration enthusiasts work year-round, bringing new trucks back to life. These aren’t static history museum pieces gathering dust. Many of these trucks run. They’re maintained, preserved, kept in working order by people who understand that these machines aren’t just objects—they’re living history.
Gary’s daughter Kathryn has taken up the torch, serving as director, curator, and tour guide.
She’s the only person who’s spent her entire life around the collection, and when she talks about these trucks, you realize you’re not just hearing about vehicles—you’re hearing about family legacy, about American ingenuity, about the machines that literally built the modern world.
The Surprises Keep Coming
Just when you think it can’t get more eclectic, you stumble upon a miniature railway looping around a pond (complete with a restored carbarn and vintage water tank). There’s a Thomas the Tank Engine being restored for the kids. Pedal cars. Old school buses you can climb aboard. A telephone booth from Newark. Signals from the old Newark City Subway.
And always, looming in the background, that massive battleship gun barrel—a reminder that this place defies categories. It’s not quite a truck museum, not quite a history museum, not quite a collection. It’s all of these things and none of these things. It’s Gary Mahan’s dream made real, brick by brick, truck by truck.
The Catch (Because There’s Always a Catch)
Here’s the bittersweet part: the Mahan Collection is only open one Saturday a month from April through October. It operates as a nonprofit, surviving on donations and the dedication of volunteers who believe this history is worth preserving.
Which means if you’re reading this thinking, “I need to see this place,” you actually need to plan for it. Mark your calendar. Clear your Saturday. Because once you know this place exists—tucked away in suburban New Jersey, protected by a small team of passionate people—you can’t not go.
Why The Mahan Collection Matters
We live in a world of streaming museums and virtual tours, where everything is accessible from our couches. The Mahan Collection is the opposite of that. It’s physical, tactile, overwhelming in the best way.
You have to show up. You have to wander. You have to let yourself get lost in buildings full of machinery and memory. You have to allow yourself time to savor all the senses from the sounds of the engines to the smells of the diesel.
And when you do, something unexpected happens.
Whether you arrived as a truck enthusiast or someone who was just curious, you leave understanding something fundamental about American history, about the machines that hauled our goods, built our infrastructure, and connected our country.
