Flatbed vs Enclosed Trailer
Compare flatbed vs enclosed trailers for trucking: costs, pros, cons, and which suits your freight. Get practical advice for 2026.
Choosing between a flatbed and an enclosed trailer is one of the first big equipment decisions you’ll make as a driver or small fleet owner. The short answer: flatbeds are cheaper, more flexible for odd-shaped loads, and faster to load, but they expose freight to weather and require tarping. Enclosed trailers protect cargo and expand your customer base, but they cost more, weigh more, and limit load dimensions. Your choice depends on the freight you want to haul and your budget. Here’s the breakdown.
Cost Comparison: Purchase, Maintenance, and Operating Costs
Initial purchase price is the biggest upfront difference. A new 48-foot flatbed trailer runs $25,000 to $40,000, while a new 53-foot dry van (the most common enclosed trailer) costs $45,000 to $70,000. Used models: flatbeds $10,000 to $20,000, dry vans $20,000 to $40,000, depending on age and condition.
Maintenance costs also differ. Flatbeds have fewer moving parts, but the wood deck needs replacement every 5 to 10 years ($1,500 to $3,000 for a new deck). Enclosed trailers have doors, hinges, and roof seals that wear out; expect annual repair costs of $500 to $1,500. Insurance premiums are higher for enclosed trailers because the cargo value is typically higher, adding $500 to $1,500 per year.
Fuel economy is similar since both are aerodynamic boxes, but flatbeds with exposed loads can catch wind, reducing mpg by 0.2 to 0.5. Overall, expect to pay $0.10 to $0.20 per mile more with an enclosed trailer when you factor in insurance and maintenance.
Load Flexibility and Freight Types
Flatbeds shine with freight that doesn’t fit in a box: construction materials (lumber, steel beams), machinery, pipes, and oversized items. You can haul loads up to 8.5 feet wide with permits, and length is limited only by your trailer. Enclosed trailers are limited to 53 feet long, 8.5 feet wide, and 8.5 feet tall inside, but they protect cargo from rain, dust, and theft.
Enclosed trailers open up general freight, palletized goods, and consumer products. You can also haul temperature-sensitive items if you add a reefer unit, but that’s a separate investment. Flatbeds require tarping for most loads, which adds 30 to 60 minutes per stop and physical labor.
Loading and Unloading: Time and Equipment
Flatbeds are easier to load with a forklift or crane from any side. Many shippers have dock-high loading for flatbeds, but you may need to use a liftgate or ramp for ground loading. Enclosed trailers require a loading dock or a liftgate, which adds cost if the shipper doesn’t have one.
Unloading is similar: flatbeds allow side access, so you can unload with a forklift from either side. Enclosed trailers only open at the rear, so you need a dock or a pallet jack with a ramp. If you haul freight that requires multiple stops, flatbeds are faster because you can access each load without moving others.
Tarping: The Hidden Time Sink
Tarping is the biggest downside of flatbeds. You must secure and tarp most loads to protect them from weather and meet DOT requirements. A typical tarp job takes 30 to 60 minutes, and in bad weather it can take longer. You need multiple tarps (each $200 to $400) and bungee cords or straps. Enclosed trailers eliminate tarping entirely, saving you 2 to 4 hours per week on average.
Comparison Table: Flatbed vs Enclosed Trailer
| Feature | Flatbed Trailer | Enclosed Trailer (Dry Van) |
|---|---|---|
| Purchase Price (New) | $25,000 - $40,000 | $45,000 - $70,000 |
| Purchase Price (Used) | $10,000 - $20,000 | $20,000 - $40,000 |
| Annual Maintenance | $1,000 - $2,500 | $1,500 - $3,000 |
| Insurance (Annual) | $2,000 - $4,000 | $2,500 - $5,000 |
| Load Access | Side and rear | Rear only |
| Tarping Required | Yes (most loads) | No |
| Freight Types | Construction, machinery, oversized | General freight, pallets, consumer goods |
| Fuel Economy | 6.0 - 8.0 mpg | 6.5 - 8.5 mpg |
| Typical Rate per Mile | $2.00 - $3.50 | $1.80 - $3.00 |
Which One Should You Choose?
If you’re starting out with a limited budget and want to haul construction or specialized freight, a flatbed is the lower-cost entry point. You’ll need to learn tarping and securement, but you can find loads easily on load boards. If you prefer steady, high-volume freight like retail goods, an enclosed trailer is worth the extra cost because you’ll have more shippers to choose from.
Consider your physical condition: tarping is demanding, and if you have back problems, an enclosed trailer is safer. Also, think about your home base: if you’re in a region with heavy rain or snow, enclosed trailers protect your cargo and reduce weather delays.
Practical Steps to Take This Week
- Calculate your budget: Add up your savings, financing options, and expected monthly payments. Use the price ranges above to estimate.
- Check load availability: Search load boards like DAT or Truckstop for your area. See which trailer type has more loads and higher rates.
- Talk to other drivers: Ask in forums or at truck stops about their experiences with both trailer types. Get real-world maintenance costs.
- Compare insurance quotes: Call two or three insurance agents with the same cargo value and see the premium difference.
- Test drive: If possible, rent a flatbed or enclosed trailer for a week to see which you prefer handling.
FAQ
Q: Can I haul palletized freight on a flatbed? A: Yes, but you need to secure each pallet with straps and possibly tarp them. It’s doable, but less efficient than an enclosed trailer.
Q: Are flatbeds more dangerous to drive? A: Not inherently, but they have a higher center of gravity when loaded, so you need to drive more carefully in curves and wind. Enclosed trailers are more stable.
Q: What’s the average lifespan of a flatbed deck? A: With proper care, a wood deck lasts 5 to 10 years. Aluminum decks can last longer but cost more upfront.
Q: Do I need a special CDL to pull an enclosed trailer? A: No, both require the same Class A CDL. The trailer type doesn’t change the license requirement.
The Bottom Line
Flatbeds and enclosed trailers both have their place. If you want lower startup costs, flexible hauling, and don’t mind physical work, go flatbed. If you prefer protected cargo, easier loading at docks, and a broader freight market, go enclosed. Run the numbers for your specific situation, and don’t rush the decision. The right trailer will pay for itself many times over if it matches your freight and lifestyle.
