The Trailmaster Flat Front distinguishes itself from the Thunder and Explorer series through a comprehensive set of standard upgrades — including 2" tall tubing roof bows, white vinyl interior finish, stainless steel door hardware, polished radius corners with a side divider strip, upgraded LED lighting, and 5,000# D-rings — all included as standard rather than optional add-ons. The trailer is also commonly optioned with a 3' V-Nose and radius top for those who want additional aerodynamic styling. The 10-year structural warranty and 25-year aluminum roof warranty reflect the premium build quality of the Legend Premium Enclosed series.
Key Features & Benefits
Heavy-Duty 2" x 6" Tube Frame
The main frame is constructed from 2" x 6" tube steel, providing a rigid foundation capable of supporting G.V.W.R. ratings up to 14,000# on the largest models. This robust frame construction is paired with 2" x 3" tube cross members spaced 16" OC, distributing load evenly across the floor for demanding cargo and equipment hauls.
One-Piece All-Aluminum Flat-Top Roof
The seamless one-piece aluminum roof eliminates seams that can become leak points over time, protecting cargo from weather. Backed by a 25-year aluminum roof warranty against corrosion and deterioration, this is a long-term investment for contractors who keep trailers in service for years.
Bonded, Screwless .040 Aluminum Exterior Skin
The exterior panels are bonded rather than mechanically fastened, producing a clean, screwless surface that resists water intrusion at fastener points and presents a professional appearance on the job site or at the track. The .040 aluminum thickness provides durability without adding unnecessary weight.
E-Z Lube Torsion Axles with Electric Brakes
E-Z Lube torsion axles simplify routine bearing maintenance, reducing downtime between jobs. Two electric brakes are standard across all models, providing reliable stopping power for loaded trailers on public roads.
Premium Interior Finish
White vinyl walls and ceiling, 3/8" wood interior wall panels with a 24" wood kickplate, and 3/4" engineered wood floor panels create a finished interior that protects cargo and withstands the wear of repeated loading and unloading. The 24" kickplate specifically guards the lower wall area where equipment and cargo most often make contact.
4 – 5,000# D-Ring Tie Downs (Installed)
Four recessed 5,000# D-rings are installed as standard, giving contractors immediate, high-capacity tie-down points for securing vehicles, equipment, or heavy cargo without aftermarket modification.
LED Lighting — Interior and Exterior
Two 12V rectangle LED dome lights with a wall switch illuminate the interior for loading and unloading in low-light conditions. Surface-mount LED exterior lighting meets road requirements and provides long service life with minimal maintenance.
36" Curbside RV Side Door with Flush Lock
The 36" curbside RV-style side door with flush lock and aluminum holdback provides convenient personnel access without opening the full rear ramp, saving time when retrieving tools or equipment mid-job.
Common Applications
General Cargo Hauling
The full 97.5" interior box width and up to 32' interior length accommodate large, bulky cargo loads for contractors moving materials between job sites.
Auto Hauling
The 90" wide x 73" tall rear ramp door and 78" interior height provide clearance for loading passenger vehicles and sports cars, making the TMF a capable enclosed car hauler.
ATV / UTV Transport
The wide ramp door and 5,000# D-ring tie-downs make loading and securing ATVs and UTVs straightforward, with the enclosed body protecting powersports equipment from road debris and weather in transit.
Powersports
Motorcycles, snowmobiles, and other powersports equipment can be loaded via the rear ramp and secured to the installed D-rings, with the enclosed aluminum body providing weather protection.
Lawn & Landscape
Landscape contractors can load mowers, blowers, and hand tools through the rear ramp door and access equipment quickly via the curbside side door without dropping the full ramp at each stop.
Construction
The heavy-duty frame, high G.V.W.R. capacity, and large interior dimensions make the TMF suitable for hauling construction tools, compressors, generators, and building materials to and from job sites.
