Designed for Vehicle Transport, Jobsite Cargo, and Commercial Builds

This trailer size is commonly used by auto haulers, general contractors, mobile service teams, and motorsport professionals. Tandem axles, electric brakes, and reinforced rear openings come standard for safely loading vehicles or equipment. Floor plans range from 8.5x16 up to 8.5x35, depending on inventory. Units are available with either ramp doors or double-door rear access. Most ramp models include a no-show beavertail to improve ground clearance when loading low-profile vehicles. The standard build includes a ¾” plywood floor, 3/8” plywood walls, and a fully undercoated chassis.

Structural Strength and Durable Access Points

Each trailer is built on the Interstate DuraFrame™ platform, using high-gauge steel, a through-frame tongue, hat-bow vertical wall studs, and Quadra-Sealed™ roof seams. Gussets are welded at all major stress points. Rear ramp doors are reinforced and rated from 2,500 to 4,000 pounds depending on the trailer. Stone guards made from extended diamond plate protect the trailer exterior. Hinges are welded for strength, and all wiring is concealed for easy customization—ideal for adding shelving, interior lighting, power systems, or tool racks.

Model Tiers Built for Work, Transport, or Upfitting

We offer these trailers in three model classes:

  • Victory: Includes welded steel components, radial tires, and a 1-year bumper-to-bumper warranty.
  • LoadRunner: Adds .030” aluminum siding, roof enhancements, and a 5-year roof warranty.
    Pro Series: Includes Dexter torsion axles, upgraded tie-down points, RV-style side door, taller diamond plate guards, and a 3-year bumper-to-bumper warranty with lifetime roof coverage.

These models are frequently customized with workbenches, electrical systems, air conditioning units, and generator hookups—ideal for mobile businesses and specialized applications across the Treasure Coast.

Braking, Towing, and Payload Considerations

Every 8.5’ wide trailer is equipped with tandem axles and electric brakes. Depending on axle type, GVWR ratings span from 7,000 to 14,000 pounds. Towing requires a Class III or higher hitch, a brake controller, and a full-size truck or commercial vehicle rated for the trailer’s loaded weight. Spring-assisted ramp doors ensure smooth and safe loading, even with heavy equipment or stacked cargo.
