The Niche Nobody Talks About Until They Need It
Anthony Durso owns a fleet of 16-foot refrigeration trailers — pull-behind units that run off a single 20-amp outlet and hold temperatures from zero to 50 degrees. The company is called Cold Ass Trailers, and its customers usually call in a panic.
A restaurant's walk-in cooler dies overnight. Santa Ana winds knock out power for two days. A florist needs extra cold space for the two weeks of the year — Valentine's Day and Mother's Day — that make or break the business. When that happens, Durso shows up, backs in a trailer, plugs it in, and the crisis is over.
"It's not really widely talked about, because it's not an everyday thing, but when it happens, you need something now," Durso said. "If you're a restaurant, you have $20-30,000 of food sitting in your freezer. If you don't get it figured out here in the next few hours, we're gonna have a problem."
The Operator Lesson: Sell the Book Before You Buy the Iron
Here's why anyone running a freight or equipment business should keep reading: Durso landed revenue before he owned the trailers to fulfill it — and then used his competitors' equipment to build a customer base while his own units were tied up.
For most people in equipment rental, the asset is the business — you buy the iron, then chase the work. Durso ran it backwards: he locked in demand first and treated ownership as the reward for proving the concept.
Step One: A Navy Contract Before the First Purchase
Durso wanted to buy two trailers but didn't want to sit on idle equipment waiting for business. Then he found a Navy bid in Washington state for two of the exact same Polar King trailers he was about to buy.
He priced the bid as if he were renting the units — knowing he'd actually own them — and won. The contract was a four-month rental that got extended another five months, for nine months total of revenue right out of the gate.
"I knew I was setting myself up for high expectations later on," he admitted, noting the easy start wasn't "the reality of this rental industry." But it gave him a nine-month runway with cash coming in.
Step Two: Rent the Competition's Trailers
With his own two trailers committed to the Navy, Durso started marketing aggressively — even though he had no available inventory. When restaurants like Chick-fil-A, McDonald's, or Raising Cane's called, he re-rented trailers from friendly competitors to fill the orders.
"I was in this rental industry, but I didn't have any rent," he said. The relationship stayed with him, held at the corporate decision-maker level rather than the store manager — so the customer couldn't easily cut him out.
Eventually the math caught up with him: "I started re-renting out trailers and then eventually I said, I'm making my competitors money, I should buy a third."
Why Friendly Competition Is a Strategy, Not a Weakness
Durso is deliberate about keeping good relationships with the handful of other California operators who do what he does. When his equipment fails or he's out of capacity, he needs them — and they need him.
There's an unspoken rule: nobody poaches customers. "We're grown men, and we have to have that conversation," he said — meaning they don't even need to have it.
TNH edge: in most freight businesses, every competitor is a threat to be undercut. In Durso's model, competitors are overflow capacity and a safety net — the reason he can tell a customer, "I can confidently say I can always get you something."
How the Business Makes Money
Durso charges a flat rate regardless of industry — flowers, food, pet food, all the same. He has a three-day minimum, but most rentals average a week, and grand openings or busy seasons can stretch to a month or two.
His posted rates:
- 3 days: $975
- 1 week: $1,500
- 1 month: $3,600
Those figures exclude delivery and generator charges (additional revenue streams), but include shelving. He also rents shelving and generators à la carte, and may add a fee for off-hours emergency deliveries.
The maintenance burden is light: keep the trailer clean, clean the condenser coils, and monitor power. He runs a temperature monitor that alerts him the moment a unit loses power — useful when, in one case, someone literally stole the power cord out of the outlet on camera.
The Liability Setup
Durso carries general liability and an inland marine policy (covering theft). His rental agreement states he's not liable for lost inventory — the unit was working and signed off on at delivery. If his own equipment fails, he brings out a replacement, his network being the backstop.
The Equipment Economics
Durso runs Polar King trailers with Govi (German) motors — chosen so every unit uses the same cords and parts. Cheaper Chinese-built trailers and King Tech motors exist; Durso even ran a King Tech trailer with a Govi motor to keep everything universal, paying a middle range.
The numbers he shared:
- New Polar King trailers: low-to-mid $40,000s (12-ft to 16-ft)
- A reported cheaper option around the high $20,000s he was excited to test
- Motor replacement: roughly $5,500–$6,000
- Motor lifespan before rotation: five to six years (one-year warranty)
- Used market: thin, occasionally found on Facebook Marketplace
That price spread drives the core question for any operator: "If I buy a trailer for 45 grand, when am I gonna make my money back?"
Where the Customers Come From
Durso built his pipeline through relationships, not cold transactions. His first real break came from joining the chamber of commerce, where the president happened to own a local Chick-fil-A who told him, "Man, where were you a couple of months ago when I needed you?" That introduction opened the door to other Southern California restaurant owners and facility operators.
He now targets restaurants, schools ("every school has a kitchen"), fairgrounds, festivals like Coachella, florists, and edible-arrangement shops. A majority of his business is emergency work, but he's pushing toward more planned rentals around predictable spikes — Valentine's Day, Mother's Day, St. Patrick's Day, Thanksgiving turkey giveaways, and grand openings.
A virtual assistant now makes awareness calls; the goal isn't to close on the spot but to be top-of-mind when the cooler inevitably goes down.
The Scaling Play
Durso has three trailers today and plans to buy two or three more in 2026. The long game is geographic: he already fields questions about coverage in Las Vegas, Phoenix, and Central California, and the model is to drop trailers into new regions where relationships already exist, hire a trustworthy driver, and secure a safe yard.
He's not rushing. "A lot of this stuff is built on relationships," he said. "They're going to use people that they know, like and trust."
The Name
The name nearly cost him. The original Cold Ass Trailers logo — with the word spelled out and a donkey — drew complaints within a week of his trailers returning from the Navy contract: three corporate restaurant customers said they couldn't have the word "ass" in their drive-thru. Because the relationships were strong, they told him directly instead of quietly dropping him.
Durso pivoted fast, rebranding the trailer wraps to read "Cold [donkey] Trailers" so it reads as cold-ass without saying it outright. He'd already spent a couple thousand dollars on wraps, website, and video that had to be redone — a self-described misfire he caught and corrected quickly. The name still works as an icebreaker: "There's the cold ass trailer guy."
The Takeaway for Operators
Durso's parting advice is pure niche-hunting: "Sometimes just talk to people and be like, dude, what's the hardest thing you're dealing with right now in your company? And just shut up and listen... finding that, be that resource, just be that reliable resource."
