Murphy's Diesel does not sell a single Cummins-branded shirt, hat, or hoodie, and it never will unless Cummins licenses one. That's the honest answer to the question that brings most people to this page, stated first and stated plainly. So why bring up Cummins at all? Because Rick spends part of one Marketplace-shopping episode admiring a 6.7 Cummins engine out loud. What he actually drives home in that day has a completely different motor. And what Murphy's actually sells is diesel-life apparel that was never trying to borrow somebody else's badge.
- Murphy's carries no Cummins-licensed or Cummins-branded merchandise. None of it, anywhere in the store.
- The line comes from a real moment: Rick calling a 6.7 Cummins-powered Jeep ambulance "bad," his word for impressive, while truck-shopping on Facebook Marketplace.
- He didn't buy that one. He bought a Mack Super-Liner 6x6 running an 8V92 Detroit instead.
- Using a company's brand name on merchandise without a license is trademark infringement, which is the plain legal reason a real Cummins shirt would need Cummins' own sign-off.
- Diesel loyalty runs Cummins, Duramax, and Power Stroke all at once in this world. Murphy's apparel doesn't pick a side between them.
- What the store actually makes: a Mountain Logo tee and long sleeve, and a "Move Over" shirt aimed at people who share the road with a wrecker.
1. The Marketplace scroll that got weird
This episode starts with Rick and his family stuck in Colorado with no way to haul their gear home, so he opens Facebook Marketplace looking for a truck. "I've got to surf marketplace and find something to drive home," he says. What follows isn't really a shopping trip. It's a parade of the strangest listings within driving distance, and you can tell he's enjoying every minute of it.
A 1979 International Harvester Scout gets vetoed for only having two seats: "not enough room for the girls." A Stewart & Stevenson military hauler loses out at $60,000 with no box on the back. A 1964 Mercedes-Benz Unimog nearly wins, purely on the strength of a fold-down desk in back where his daughter could do schoolwork. Nice detail, that one. Then Rick scrolls past a listing that stops him mid-sentence.
2. "Anything with a 6.7 Cummins is bad," and what that means
The listing is a 1967 Jeep body dropped onto a RAM chassis, built out as an ambulance, running a 6.7-liter Cummins. Picture that for a second. Rick isn't sold on the Jeep part. He's very sold on the engine, and you can hear exactly which one wins.
"Anything with a 6.7 Cummins is bad, if you ask me. There's plenty of room for the gals. It's got a winch on the back. You want two?"Wrecker Rick, scrolling Facebook Marketplace
"Bad" here means the opposite of what it sounds like. It's the same as "bad Larry" for a favorite truck: in Rick's vocabulary, it's about the highest compliment an engine gets. That reaction isn't unique to him, either. Diesel trucks build entire identities around which engine sits under the hood. Notice the loyalty here: the Cummins inline-six that's powered Dodge and Ram trucks for decades has as devoted a following as any of them. A shirt that plays to that loyalty by name is chasing something real. Murphy's apparel just isn't that shirt.
3. The honest part: no Cummins badge here
Cummins is a trademark that Cummins Inc. owns, and putting a company's brand name or logo on merchandise without permission is what trademark law calls infringement. The U.S. Patent and Trademark Office defines it plainly: infringement is "the unauthorized use of a trademark or service mark on or in connection with goods and/or services in a manner that is likely to cause confusion" about who's actually behind the product. Murphy's has never sought, and doesn't have, a license from Cummins to put that name or logo on a shirt. So it doesn't.
That's not a workaround. It's not fine print, either. It's the actual answer to "does Murphy's sell a Cummins shirt": no, and it's on purpose. Doing it without permission is the kind of thing that gets a small apparel line a letter from a much bigger company's lawyers. If you landed here looking for officially licensed Cummins gear, you're better off knowing that up front than finding out at checkout.
4. Diesel life is bigger than one engine brand
Rick's own truck history makes the point better than a tagline could. He spends that entire episode admiring a 6.7 Cummins. Then he drives home in a Mack Super-Liner 6x6 running an 8V92 Detroit, a completely different engine family. The channel doesn't plant a flag on one badge and defend it. It runs whatever gets the job done: Cummins, Detroit, or otherwise.
That's closer to what Murphy's apparel is actually selling. Not a specific engine's fan club. The wider identity of running diesel equipment for a living, or just loving it from the driveway. Whichever one you run, a Duramax, a Power Stroke, a Cummins, you can wear the same shirt, and you're not wrong for it.
5. What's actually in the closet
Three pieces cover most of what the channel's apparel line is actually doing, and two of them are better documented than most shirts on the internet. The Mountain Logo Shirt and its long sleeve version are both built on a Next Level 3600 tee. Murphy's own product page gets specific: 100% combed ring-spun cotton. The heather grey colorway runs a 90% cotton, 10% polyester blend instead. Weight's 32 singles. One fit note before you order: "these shirts do run a tight fit." Good to know before you're stuck between sizes. Both shirts carry the same Mountain Logo with an American flag detail on the sleeve, and the product page asks that you wash them inside out to protect the print. The "Move Over" shirt is its own thing entirely: a message aimed at the traffic Rick's wreckers work around every day.
"Seriously though.... move over when we are working on the road!"Move Over shirt product page
Next Level 3600 tee, 100% combed ring-spun cotton, 32 singles weight. Runs tight per the product page. Mountain Logo with an American flag detail on the sleeve, no engine badge, no borrowed brand.
Next Level 3600, 100% combed ring-spun cotton, 32 singles. Product page notes it runs tight. The default pick if you only buy one.
A message for the traffic Rick's wreckers share the road with every day, not an engine badge of any kind.
Same Next Level 3600 build, cotton, and flag detail as the short sleeve, in long-sleeve form for the months a tee doesn't cut it.
6. The bottom line
Rick called a Cummins engine "bad" on camera and meant it as praise. Murphy's still doesn't sell a Cummins shirt, and saying so plainly beats pretending otherwise. What the store sells instead: the Mountain Logo Shirt at $29.99 to $39.99, the Mountain Logo Long Sleeve at $34.99, and the Move Over shirt at $34.99. All three are diesel-life apparel for the whole world Rick drives through, not a badge for one engine inside it.
The truck he actually bought that day ran an 8V92 Detroit, not the Cummins he'd been admiring. Kind of a nice punchline, if you think about it. Nobody checks an engine badge before deciding whether you belong in this world. The shirt shouldn't either.
