Trailmaster 3V Tandem Axle Cargo Trailer

Trailmaster 3V Tandem Axle Cargo Trailer — Premium All-Aluminum Enclosed Hauling

The Trailmaster 3V (TM3V) is a premium all-aluminum enclosed cargo trailer featuring a 3′ V-Nose, engineered for contractors and trades professionals who demand durability and versatility. Available in nine tandem axle configurations from 8.5x19 to 8.5x35, it supports G.V.W.R. ratings from 7,000# to 14,000# to handle everything from general cargo and construction materials to vehicles and powersports equipment. The TM3V represents a significant upgrade over the Thunder/Explorer series, incorporating enhanced structural components, upgraded interior finishes, and heavy-duty tie-down hardware as standard equipment.

Axle & Running Gear by Model

Compared to the Thunder and Explorer series, the Trailmaster 3V steps up with 2″ tall tubing roof bows, white vinyl walls and ceiling, a 24″ interior kickplate, stainless steel door hardware, bright polished radius corners with a side divider strip, upgraded interior LED lighting, and 5,000# D-Rings installed as standard — making it the premium choice for professionals who need a more refined, work-ready enclosed trailer without ordering a custom build.

Key Features & Benefits

Bonded, Screwless .040 Aluminum Exterior Skin

The exterior panels are bonded rather than mechanically fastened, eliminating exposed screw heads that can loosen, leak, or corrode over time. The .040 aluminum thickness provides a rigid, dent-resistant surface that holds up to jobsite and road conditions while maintaining a clean professional appearance with the included accent strip and decal.

One-Piece All-Aluminum Roof with 25-Year Warranty

A seamless one-piece aluminum roof eliminates seams and joints that are common leak points on multi-panel roofs. The 25-year manufacturer's warranty on the aluminum roof against corrosion and deterioration reflects the long-term confidence in this construction — a meaningful assurance for contractors who depend on their trailer year-round.

E-Z Lube Torsion Axles

Torsion axles provide independent wheel suspension, delivering a smoother ride that reduces stress on cargo and the trailer frame over long hauls. The E-Z Lube design simplifies routine bearing maintenance, helping contractors keep the trailer in service with minimal downtime.

4 Installed 5,000# D-Ring Tie Downs

Four heavy-duty 5,000# D-rings are installed as standard, providing secure anchor points for strapping down vehicles, equipment, or palletized cargo. Having these pre-installed means the trailer is ready to work immediately without additional hardware purchases or modifications.

2″ x 6″ Tube Main Frame with 16″ OC Structural Spacing

The heavy-gauge 2″ x 6″ main frame tube, combined with 2″ x 3″ cross members, wall studs, and roof bows all spaced at 16″ on center, creates a rigid, well-supported structure capable of handling the G.V.W.R. ratings up to 14,000#. This consistent structural spacing also simplifies interior modifications or accessory mounting for contractors who customize their trailers.

36″ Curbside RV Side Door with Flush Lock & Aluminum Holdback

The 36″ curbside RV-style side door provides convenient walk-in access without opening the full rear ramp, saving time when retrieving tools or equipment mid-job. The flush lock and aluminum holdback keep the door secure during transit and held open during loading operations.

Dual 12V LED Interior Dome Lights with Wall Switch

Two 12V rectangle LED dome lights with a dedicated wall switch provide reliable interior illumination for loading and unloading in low-light conditions. LED technology draws less power than incandescent alternatives, reducing drain on the tow vehicle's electrical system during extended use.

Common Applications

General Cargo Hauling

The enclosed design and wide 97.5″ interior box width accommodate palletized goods, bulk materials, and oversized cargo securely protected from weather and road debris.

Auto Hauling

The 90″ wide ramp door, 78″ interior height, and 5,000# D-ring tie downs make the TM3V well-suited for transporting passenger vehicles, project cars, or race vehicles to and from events or job sites.

ATV / UTV Transport

The ramp door and wide interior accommodate side-by-side UTVs and ATVs, with D-ring tie downs providing secure restraint during transport across all nine available length configurations.

Powersports

Motorcycles, snowmobiles, and personal watercraft can be loaded via the rear ramp and secured to the installed D-rings, with the enclosed body protecting equipment from road grime and weather.

Lawn & Landscape

Landscaping contractors can load mowers, blowers, trimmers, and hand tools with the rear ramp door, keeping equipment secured and out of sight between job sites.

Construction

The TM3V serves as a mobile tool and material storage solution for construction crews, with the side door providing quick access to frequently used tools without unloading the full trailer.
