Enclosed vs Open Utility Trailer: Which Do You Need?
This is the first decision most trailer shoppers make: a closed box or an open deck. An enclosed trailer wraps your load in walls, a roof, and lockable doors; an open utility trailer is a flat deck you load from any side. The enclosed one protects and secures; the open one is cheaper, lighter, easier to tow and load, and handles most everyday hauling. What you carry — and whether it has to stay dry and locked — usually decides it.
| Enclosed | Utility | |
|---|---|---|
| Best for | Valuable, weather-sensitive, or secured cargo — motorcycles, tools, household moves, mobile/vending business. | General open hauling — yard and landscaping waste, appliances, furniture, mowers and ATVs, dump runs. |
| What it hauls well | Anything that must stay dry and locked; doubles as lockable storage or a workspace. | Bulky, dirty, or heavy open loads you load from the side or top and can shovel or drive on and off. |
| Weather / dust protection | Full — walls and roof keep out rain, dust, and road debris. | None — loads are exposed and must be tarped if weather-sensitive. |
| Security | Lockable doors; contents hidden from view — good for tools, bikes, and valuables. | Open and visible; relies on tie-downs, not locks. |
| Typical size range | 5×8 single-axle up to 7×16, 8.5×20, 8.5×24 tandem. | 4×6 and 5×8 up to 6×12 and 7×16; single or tandem axle. |
| Towing / wind resistance | Tall, boxy profile → more wind drag and lower fuel economy; mind height and clearance. | Low, open profile → minimal drag; the easiest type to tow with most vehicles. |
| Relative cost | Costs more than an open trailer of the same footprint — you’re paying for walls, roof, and doors. | The cheapest, simplest trailer type — lowest entry cost and lightest to tow. |
| Maintenance | More surfaces to keep up — door seals, roof, interior — but cargo stays protected. | Minimal — the open deck, tires, and lights; nothing to seal or weatherproof. |
Choose Enclosed if…
- You haul valuable or weather-sensitive cargo
- You need security or a lockable, weatherproof space
- You move household goods or run a mobile business
- You want a trailer that doubles as storage or a workspace
Choose Utility if…
- You do general open hauling — yard work, dump runs, moving bulky items
- You want the lowest cost and the easiest towing
- Your loads are weatherproof, or you’ll tarp them
- You haul occasionally or a bit of everything
What about cost?
An open utility trailer is almost always the cheaper trailer up front — it’s the simplest build and the lightest to tow. An enclosed trailer costs more because you’re paying for walls, a roof, doors, and the weather protection and security they buy. But “cheaper trailer” isn’t the same as “cheaper for you”: how often you’ll haul, storage, and upkeep move the real math — and for occasional use, renting either type often beats owning.
