Reefer trucking for owner-operators

Reefer is the trailer for owner-operators who like to plan. The freight follows harvests and holidays, the rates are higher than dry van, and the loads are time-sensitive in a way that rewards a driver who shows up on time with a cold trailer. The trade-offs are a second diesel engine to feed, night and weekend appointments, and claims that can cost more than the load paid.

What reefer trucks haul

SOURCE: Ranges are typical industry practice, not rules; always run the set point on the bill of lading. Product-by-product set points: reefer temperature settings.

Continuous mode keeps the unit running and air moving all the time. Cycle mode lets the unit shut off when it reaches the set point, which saves fuel but lets temperatures drift. Most fresh and frozen food ships continuous.

The rig and its extra costs

80,000 LB GROSS INCLUDING THE UNIT AND ITS FUEL

A reefer trailer is insulated, heavier than a dry van and carries a diesel refrigeration unit with its own fuel tank. That adds up in three places:

• Payload. The unit, insulation and reefer fuel come out of your 80,000 lb gross, so a reefer usually carries a little less than a van.
• Fuel. The unit burns diesel by the hour, moving or parked. See reefer fuel consumption for burn rates.
• Maintenance. Unit service, trailer washouts and seals are costs a dry van owner doesn't pay.

Where reefer loads start, by season

Reefer freight begins where food is grown, packed or stored. Planning a reefer year means knowing which region ships when, then booking the reload back toward it.

Meat, dairy and frozen food move all year and steady the calendar. Thanksgiving and year-end holiday food add a push in November and December.

Reefer rates in 2026

DAT's national reefer spot average was a record $3.62 a mile in September 2026, fuel included, and $2.70 without fuel. Contract reefer averaged $3.58. Reefer was also the only one of the three main trailer types where linehaul rose from August to September. Dates, weekly figures and the seasonal comparison are on reefer rates per mile.

Claims: the reefer risk nobody posts

A dry van claim usually means damaged boxes. A reefer claim can mean a whole trailer of rejected food. Most come from a few avoidable mistakes:

1. Wrong set point. Check the bill of lading against the unit display before you leave the dock, and photograph both.
2. No pre-cool. Shippers expect the trailer at temperature when you back in.
3. Cycle instead of continuous. Run the mode the shipper asks for.
4. Doors open too long at multi-stop deliveries.
5. Warm product loaded. Note the product temperature on the bill of lading if it's off, before you sign.
6. Running low on reefer fuel. An empty unit tank on a hot day ends badly.

Receivers can download the unit's temperature record, so the record protects you as much as it protects them. Shippers usually spell out food-safety duties for the carrier in their contract, under FDA's sanitary transportation rule. Ask what yours requires.

Worked example: a reefer week

REEFER WEEK, EXAMPLENO. 0143

EXAMPLE

Loads

3 (produce out, meat back, short dry reload)

Gross revenue

$8,600

Loaded + empty miles

2,450 + 250

All-in rate

$3.19/mi

Truck fuel at 6.5 mpg, $6.29

$2,613

Reefer unit fuel, EXAMPLE 70 gal

$440

Lumpers (reimbursed)

$0 net

Waiting hours unpaid

5

Left before fixed costs and pay$5,547

This EXAMPLE week runs produce out of a growing region, a meat load back toward home and a dry load to fill a gap. The rates look strong; unit fuel and five unpaid hours at a cold-storage dock are where the margin leaks. Insurance, truck and trailer payments, maintenance and your own pay still come out of what's left. Price your fuel with the trip fuel cost calculator.

Is reefer trucking profitable?

For owner-operators who plan, often yes. The ones who do well follow the harvest instead of fighting it, keep a short list of shippers and brokers in each region, insist on detention terms for long dock waits and protect themselves with good temperature records. The ones who struggle chase the highest posted rate into a region with no outbound freight, or take one claim that wipes out a month.

What it means for the loads you book

• Read the set point and mode first. Then the rate.
• Ask about appointment times at both ends. Night appointments are common.
• Get detention and lumper terms on the rate con.
• Check the reload from the delivery city before you accept.
• Watch weight. Dense frozen and beverage loads can hit the axle limits sooner on a heavier reefer trailer.

Dispatch for reefer owner-operators

The planning that makes reefer pay takes hours on the phone: which region is shipping, which brokers have the produce, what reload gets you home. Our reefer dispatching service does that work and checks temperatures, appointments and detention before a load reaches you. You get the full details, you accept or pass, and the broker's rate con comes directly to you for your signature.
