Key Enclosed Cargo Trailer Features

DuraFrame™ Design

Our exclusive DuraFrame™ design means your Interstate cargo model is built to last. Interstate, the manufacturer, uses only the highest gauge American steel. The trailer’s tongue frame passes through the chassis and is welded to the main rails for more security and optimal strength.

Dexter Axles

Interstate trailers are built with American-made Dexter Axles, the quality leader in the industry for over 50 years. Each is constructed with either heavy-duty leaf spring axles or rubber-dampened torsion axles that provide independent wheel suspension and superior handling.


From our sturdy steel-framed door openings to the strength-reinforcing gussets on our corner posts, our I-beams are made from the same steel American skyscrapers are built with. Structurally fortified in all the right places, Interstate’s frame strength is unmatched.

One-Piece Aluminum Roof

We utilize a one-piece aluminum roof with Quadra-Sealed™ four-layer roof seams that keep moisture out, ensuring that your cargo stays dry. An internal roof liner prevents roof vibration and wear, as well as formed steel internal frames and welded ridge reinforcements, making the roof of an Interstate trailer as strong as the rest of the model.

Commercial Strength Floor and Walls

Interstate’s doors and ramps feature heavy-duty welded hinges. Most manufacturers use lower-grade bolts and straps that bend and sag over time, but Interstate’s steel door frame can’t be bent. With ramps rated from 2,500 to 4,000 pounds that are fortified with steel gussets and three-piece welded hinges, Interstate units can handle the heaviest cargo.

Sealed Flooring System

The steel chassis is protected by automotive-grade paint, and all-weather protective undercoating comes standard on all Interstate models. With ¾” thick exterior grade plywood from northwest-grown Douglas Fir, our floors are solid, and the seams are completely sealed to keep moisture out.

Diamond Plate Stone Guard

The Interstate brand delivers quality and durability. That’s why we install diamond plate stone guards on all our Interstate cargo trailers. These guards prevent debris damage and ensure your unit stays in showroom condition for years to come. In addition, they increase your model’s curb appeal.

Hat-bow Stud Design

We utilize a hat-bow vertical stud design to give your model increased strength and the best resistance to flexion. As opposed to a tube beam design, a hat-bow stud design provides a larger contact surface area. More surface area contact gives you a sturdier experience, leading to a longer life and safer driving.


Interstate’s added gussets mean your cargo trailer is made with durability in mind. These reinforcements add exponential strength to your trailer, resisting flexion and providing a more durable design. We don’t take shortcuts when it comes to construction.

Radial Tires

All Interstate models come equipped with radial tires. Radial tires offer a longer life and increased fuel mileage. Radial tires are much less prone to blowouts.

⅜” Plywood Interior Walls

Every Interstate cargo unit has ⅜” plywood interior walls to give years of reliable use. Connected to our hat-bow studs and ¾” plywood floor, this is a recipe for a strong and sturdy unit. Install e-tracks, tie downs, or build shelving. These heavy-duty walls will handle it with ease.

Concealed Wiring

Not only do we provide quality and durability, but we give our models curb appeal, too! Why have a perfectly constructed trailer with exposed wiring? We conceal all wiring to make our models seamless from the outside in.

Spare Tire Mount

Don’t be caught on the side of the road without a spare tire! We provide a spare tire mount on the right side of the rear door, which is easily accessible in any road emergency. We install our spare tire mounts off the floor to prevent them from detracting from your precious cargo space.


We believe in the quality of our units and models, which is why we offer the Interstate Limited Trailer Warranty. This warranty provides peace of mind, with coverage tailored to our diverse inventory. Feel confident knowing your investment is protected, with clear provisions for warranty service and exclusions explained for your understanding.

For example, our Pro Series models include a lifetime roof warranty and a 3-year bumper-to-bumper protection. Ask our team for specific warranty details on the model that interests you.
