Reefer Freight Surge: Why Owner-Ops Should Consider Temperature-Controlled Work Now

The reefer market is heating up—literally and figuratively. Recent earnings reports from major carriers show temperature-controlled freight is outpacing dry van, and spot rates for reefer loads are climbing as summer produce season hits hard. For owner-operators running dry van or considering a side venture into reefer, now is a practical moment to do the math and understand what it takes to compete in this lane.

Why Reefer Rates Are Rising Right Now

Produce season runs roughly May through October, with peak demand in July and August. Shippers moving perishables—fresh fruit, vegetables, dairy, frozen goods—cannot wait for cheaper capacity. A load of strawberries or lettuce has a shelf life measured in days, not weeks. That urgency translates into higher rates and steadier freight flow compared to dry van spot markets, which can swing wildly based on overall freight supply.

Marten Transport, one of the largest reefer carriers in North America, reported strong Q2 earnings tied directly to reefer demand. When a major carrier sees margin improvement in a specific lane, smaller operators and owner-ops typically see better rates follow. The window is now, and it typically narrows after September.

The Real Cost of Running Reefer

Before you call a reefer trailer dealer, understand the economics. A temperature-controlled unit costs more to operate than dry van:

Equipment: A used reefer trailer runs $15,000–$30,000 depending on age and condition. A new unit is $45,000–$60,000. Lease rates (if you don't own) are typically $800–$1,200 per week, depending on market and trailer condition.

Fuel: Reefer units burn diesel to run the refrigeration system—roughly 10–15% more fuel consumption than a dry van pulling the same distance. At current fuel prices, that's a meaningful margin hit.

Maintenance: Reefer units require specialized service. Compressors, evaporators, and electrical systems are more complex than dry van. Budget $2,000–$4,000 annually for preventive maintenance, plus emergency repairs that can run $500–$2,000 per incident.

Compliance: Reefer loads often have tighter temperature and humidity specs, meaning more frequent inspections and documentation. Some shippers require GPS tracking and real-time temperature logs—another tech cost.

Rate Math: When Reefer Pencils Out

Here's the practical threshold: reefer loads typically pay 15–25% more per mile than comparable dry van freight, depending on lane and season. Right now, in peak season, some reefer rates are hitting $3.50–$4.20 per mile on major produce lanes (California to East Coast, for example), versus $2.80–$3.40 for dry van.

But the math only works if you:

1. Run consistent loads, not sporadic reefer mixed with dry van. Switching between refrigerated and non-refrigerated freight wastes time and money on cleaning, inspections, and equipment idle time.
2. Minimize deadhead. Reefer lanes are concentrated (produce regions, distribution hubs, cold-storage facilities). If you're hauling from the Midwest to California, you'll likely backhaul empty or find a return load quickly. A loadboard like Doft can help you spot return reefer or dry van freight in real time, cutting wasted miles.
3. Own or long-term lease your trailer. Paying $1,000+ per week in lease fees erodes the rate premium fast. If you're only running reefer seasonally (May–September), ownership or a flexible short-term lease makes more sense than a long-term commitment.

Is Reefer Right for You?

Reefer makes sense if:

• You're based near or willing to operate in produce regions (California, Florida, Texas, the Pacific Northwest, or major distribution hubs).
• You can commit to running temperature-controlled freight consistently for at least 3–4 months.
• You have access to reliable maintenance (reefer units break down, and downtime kills earnings).
• You can manage the regulatory and documentation overhead (some shippers are strict about temperature compliance).

Reefer does not make sense if:

• You're a long-haul cross-country operator who values flexibility and variety. Reefer locks you into specific lanes and shippers.
• You lack capital or credit to buy or lease a trailer. Paying top-dollar lease rates narrows your margin too much.
• You're in a region with weak reefer infrastructure or few cold-storage facilities.

How to Test the Waters

If you're curious but not committed, consider these low-risk entry points:

1. Lease a reefer trailer for one month during peak season (July or August). Run loads aggressively and track your all-in cost per mile—fuel, lease, maintenance, empty miles. Compare your net margin to dry van rates in your market. If you clear 20%+ more per mile after all costs, reefer might be worth a longer commitment.
2. Partner with a shipper or broker who specializes in reefer. They often have consistent lanes and can help you understand the load flow and rate stability in your region.
3. Use a loadboard to scout rates in your area. Doft and similar platforms show real-time reefer rates alongside dry van, so you can see the actual premium available before you invest.

The Takeaway

Reefer freight is strong right now, and that strength will likely hold through August. But it's not a universal upgrade—it's a specialized lane that pays better only if you run it efficiently and consistently. If you're in or near a produce region, have capital to invest in a trailer, and can commit to 3–4 months of focused reefer work, the math can work very well. If you're a generalist owner-op who values flexibility, dry van spot rates are also at historic highs, and you may be better served sticking with what you know.

Do the math for your specific situation, talk to other reefer operators in your area, and use real-time rate data to make an informed call. The window is open, but it's seasonal—so move fast if you decide to move.
