An 8.5×16 enclosed trailer is an excellent choice for customers who need maximum width and increased cargo capacity without moving into a much longer trailer. The full 8.5-foot width provides significantly more interior space than a 7-foot-wide model, making it ideal for hauling larger equipment, vehicles, inventory, tools, motorcycles, side-by-sides, or multiple ATVs. The wider interior also allows for easier loading, better organization, and additional room to move around inside the trailer. Most 8.5×16 trailers are equipped with tandem axles, providing improved stability, better weight distribution, and greater towing confidence when transporting heavier loads or traveling longer distances.
This size is a popular choice for contractors, construction crews, mobile businesses, motorsports enthusiasts, and customers who need the extra width for larger cargo or enclosed workspaces. An 8.5×16 offers an excellent balance of cargo capacity, versatility, and towing practicality, making it a dependable option for both commercial and recreational use while remaining easier to maneuver than longer 20-foot or 24-foot enclosed trailers.
Typical dimensions on a 8.5×16 enclosed trailer can vary slightly by manufacturer, but most models feature an interior width around 96–97 inches and an interior height between 82–84 inches (roughly 6’10” to 7′ tall). At Western States Trailer, customers can also customize trailer height when additional clearance is needed for taller cargo, shelving systems, side-by-sides, or specialized equipment setups.
Most 8.5×16 models are equipped with tandem 3,500 lb axles, though heavier-duty axle packages are often available for increased payload capacity. Rear ramp door openings are commonly around 91–93.5 inches wide and 79.25–84 inches tall depending on the roof style and trim package. These larger door dimensions make loading motorcycles, side-by-sides, ATVs, golf carts, lawn and landscaping equipment, pallets, tool carts, and small equipment much easier than with narrower enclosed trailers, while also providing more room to organize and secure your cargo.
A 8.5×16 trailer also offers enough interior space for optional upgrades like built-in cabinets, E-track tie-down systems, spare tire mounts, upgraded lighting, insulation, workbenches, or mobile business conversions while still remaining manageable for everyday towing and storage.

An 8.5×16 enclosed trailer is a highly versatile trailer size that offers the extra width needed for larger cargo while remaining easier to tow and maneuver than longer commercial trailers. The spacious interior and tandem axle design make it well-suited for hauling heavier equipment, larger recreational vehicles, and high-volume cargo, making it a popular choice for both personal and commercial applications.
Common uses for an 8.5×16 enclosed trailer include:
Many customers also choose an 8.5×16 because the full-width interior provides additional space for shelving, cabinets, workbenches, tool storage, and custom layouts. The extra width makes loading, organizing, and accessing cargo easier while offering a great balance between cargo capacity and towing practicality.
While an 8.5×16 enclosed trailer offers generous cargo space and a full-width interior, it may not be the best choice for every application. Customers hauling full-size vehicles, multiple large side-by-sides, skid steers, oversized commercial equipment, or exceptionally long cargo will often benefit from a longer trailer, such as an 8.5×20 or 8.5×24, to provide additional floor space, weight distribution, and loading clearance.
An 8.5×16 may also be larger than necessary for occasional light-duty use, such as hauling a single motorcycle, a few household items, or basic storage needs. In these cases, a smaller 6-foot-wide or 7-foot-wide enclosed trailer can be a more economical option that’s easier to tow, park, and store. As with any trailer, choosing the right size depends on the type of cargo you plan to haul, your tow vehicle’s capacity, and whether you anticipate needing additional space for future equipment or business growth.
When shopping for an enclosed trailer, one of the biggest decisions is choosing between a ramp rear door and barn doors. Ramp door enclosed trailers are ideal for loading ATVs, motorcycles, lawn equipment, side-by-sides, and other wheeled cargo because the rear door folds down into a convenient loading ramp. This makes loading and unloading fast, safe, and efficient without needing additional equipment. Barn door enclosed trailers, on the other hand, feature two swing-open rear doors and are often preferred for contractors, cargo hauling, and situations where space behind the trailer is limited. Barn doors are lighter, provide easier walk-in access, and can be more convenient when parked in tight areas. Choosing between a ramp door vs barn door enclosed trailer ultimately depends on how you plan to use your trailer, the type of cargo you haul, and how often you need ground-level loading access.
Barn-style doors on an enclosed trailer are a popular option for customers who prioritize simplicity, durability, and maximum interior clearance. Instead of a fold-down ramp, barn doors swing open from the center, making them ideal for loading hand-carried cargo, tools, boxes, motorcycles with portable ramps, or equipment loaded by forklift. Many customers also prefer barn doors because they reduce overall trailer weight, eliminate the space needed for a ramp door to fold down, and can be easier to open in tight parking areas or storage spaces. For businesses and contractors, barn doors also provide quick access to cargo without needing the extra room behind the trailer required for a full rear ramp deployment.
Ramp doors are one of the most popular rear door options for enclosed trailers because they make loading and unloading wheeled equipment fast and convenient. Customers hauling motorcycles, ATVs, side-by-sides, lawn equipment, carts, toolboxes, or rolling equipment often prefer a ramp door because it eliminates the need for separate loading ramps. The fold-down design creates a smooth transition into the trailer, making loading safer and more efficient for both personal and commercial use.
Many customers also choose a ramp door for the added versatility it provides. In addition to simplifying cargo loading, the ramp can double as a temporary work platform or staging area at events, job sites, or racetracks. For anyone frequently loading heavy or wheeled equipment, a rear ramp door is often the most practical and user-friendly enclosed trailer configuration.
