Power Only vs Dry Van: Is Trailer-Free the Way to Go? (2026)

Power only's defining advantage: you don't buy, lease, maintain, or insure a trailer. Your total investment is the tractor, bobtail insurance, and operating authority. This saves $8,000–$15,000 on a used trailer purchase, $1,500–$3,000/year in trailer insurance, and $2,000–$4,000/year in trailer maintenance. For cash-strapped operators, eliminating the trailer from the equation is a significant financial relief.

Dry van pays substantially more per mile because you're providing both power and trailer. Power only operators are paid only for the tractor — the shipper or broker provides the trailer. The $0.75/mile gap is significant: on 10,000 monthly miles, that's $7,500 less gross revenue. However, power only operators run more miles on average (10,000/month vs 8,500 for dry van) because they spend less time at loading docks and more time driving.

Dry van wins on freight availability, but power only has been growing rapidly. Amazon, Walmart, and large 3PLs increasingly use trailer pool models where they own thousands of trailers and just need tractors to move them. Port drayage (container chassis) is essentially power-only work. The trend toward asset-light carrier models benefits power only operators, but the market is still smaller than traditional dry van.

Power only simplifies the owner-operator business model. No trailer maintenance decisions, no trailer inspections to schedule, no worrying about trailer damage claims. You hook up to a pre-loaded trailer, move it, drop it, and hook up to the next one. The reduced operational complexity lets you focus on driving and route optimization. The learning curve is shorter and the operational headaches are fewer.

Power only home time depends entirely on the model you run. Relay systems (like Amazon Relay) can offer predictable regional routes with regular home time. Container drayage is typically local. But traditional power only loads on the spot market can send you anywhere with inconsistent routing. Dry van has the advantage of choosing your own lanes since you carry your trailer. Neither clearly wins — it depends on the specific operation.

No trailer means no trailer maintenance, no trailer tires to replace ($800–$1,200 per tire x 8 tires), no trailer brakes, no trailer lights, no annual trailer inspections. Your only equipment is the tractor. The savings are real: $2,000–$4,000/year less in maintenance costs. However, frequent hooking and unhooking from different trailers can accelerate wear on your fifth wheel, gladhands, and air line connections.

The power only market is the fastest-growing segment of truckload freight. Amazon, Walmart, Target, and major 3PLs are investing billions in trailer pools and need tractors to move them. The shift toward drop-and-hook operations (vs live loading) naturally favors power only. Container drayage at ports is structurally undersupplied with tractor capacity. This trend should accelerate through 2030.

Power only is ideal for operators who want to minimize capital investment, simplify operations, and capitalize on the growing trailer pool economy. Dry van is ideal for operators who want to maximize per-mile earnings, own their capacity, and have full control over which loads they take. Many operators start power only to build capital, then buy a trailer after 12–18 months.
