Shop 8.5×20 Enclosed Cargo Trailers
Need more width and cargo space? An 8.5×20 enclosed trailer provides a full-width cargo area suited for vehicles, motorcycles, equipment, contractors, mobile workspaces and a wide range of commercial and recreational applications.
Southern Trailer Depot offers 8.5×20 enclosed trailers in multiple configurations, along with available upgrades and custom-build options to match how you plan to use your trailer.
Why Choose an 8.5×20 Enclosed Trailer?
An 8.5×20 enclosed trailer provides substantially more usable width and floor space than narrower 6-foot and 7-foot-wide trailers.
The additional width makes the 8.5×20 particularly useful when cargo dimensions, equipment width or interior workspace are important.
Depending on configuration and weight capacity, common applications include:
- Cars and automotive use
- Motorcycles
- ATVs and UTVs
- Contractor tools and equipment
- Lawn and landscaping equipment
- Mobile workshops
- Business equipment and inventory
- Recreational equipment
- General-purpose cargo
Buyers should consider both the physical dimensions of their cargo and its loaded weight when selecting an 8.5×20 trailer.
8.5×20 Trailer Dimensions
An 8.5×20 enclosed trailer provides a nominal 20-foot cargo body with the additional width associated with an 8.5-foot-wide trailer.
Useful reference dimensions from our existing 8.5×20 guide include:
- Nominal size: 8.5' × 20'
- Interior width: approximately 8'
- Rear opening width: approximately 7'6"
- Interior height: available up to approximately 9', depending on configuration
Actual dimensions vary by manufacturer, model, interior height, door configuration, V-nose design and installed options. Buyers should verify the specifications of the individual trailer before purchase.
See our complete 8.5×20 Enclosed Trailer Guide for detailed measurements, axle information, cargo considerations and buying advice.
What Can You Use an 8.5×20 Trailer For?
The combination of an 8.5-foot-wide body and 20-foot cargo length makes this size useful for customers who need substantially more working or hauling space than a typical 7-foot-wide enclosed trailer.
An 8.5×20 can be configured for many different applications, including automotive use, motorcycles, recreational equipment, contractor equipment and mobile business applications.
The correct setup depends on cargo dimensions, loaded weight, required payload, axle package, door configuration and tow vehicle.
Choose the Right Axle Package and Payload
Trailer size alone does not determine how much cargo an 8.5×20 can safely carry.
Buyers should compare the trailer's GVWR, GAWR, empty weight and available payload with the weight of the cargo and any permanently installed equipment or upgrades.
Depending on the specific trailer and manufacturer, different axle packages may be available.
Heavier equipment, cabinets, generators, electrical systems, finished interiors, air conditioning and other upgrades add weight and can reduce available cargo payload.
See our Trailer GVWR, Weight and Payload Guide for a detailed explanation of GVWR, GAWR and axle packages.

Compare an 8.5×20 Before You Buy
An 8.5×20 may be a good fit when a buyer needs the width of an 8.5-foot-wide trailer but does not need the additional length of an 8.5×24.
Customers hauling smaller loads or who place greater importance on maneuverability may also want to compare an 8.5×16.
