Interstate Trailers for Sale at TrailersPlus: The Toughest Cargo Trailers On The Planet


Built Like a Tank

"Heavy Duty" comes standard

Our exclusive DuraFrame™ design means your Interstate cargo trailer is built to last. Interstate uses only the highest gauge American steel, and we don't take short cuts when it comes to construction. The tongue frame passes through the chassis and is welded to the main rails for superior strength.


Road Hugging Axles & Tires

Ready for whatever road your take

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


Hidden Strength

Structurally fortified in all the right places

From our sturdy steel-framed door openings to the strength-reinforcing gussets on our corner posts. Our Ibeams are made from the same steel American sky-scrapers are built with, making Interstate's frame strength unmatched. All exclusive components of our DuraFrame™ trailer design system.


Our Trailers Don’t Leak. Period.

Our no-leak warranty gives you peace of mind

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


Commercial Strength Doors & Ramps

Doors and ramps that can handle heavy use every day

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


Sealed Flooring System

Designed with real road hazards in mind

The steel chassis are protected by automotive-grade paint, and all-weather protective undercoating comes standard on all Interstate models. With 3/4" thick exterior grade plywood from northwest grown Douglas Fir, our floors are solid and the seams are completely sealed to keep moisture out.

"I've had many trailers of various types. This is my first Interstate. I love it. The price was very fair, the quality is by far the best I've ever seen. I will never buy anything but an Interstate if I need another trailer. The young men that assisted me were outstanding! Fernando and Matt went far and beyond to ensure my needs were met. Answered all of my questions and then some. I would like to thank TrailersPlus and the young men that sold me an exceptional Interstate trailer. I would recommend TrailersPlus and Interstate trailers to everyone. Thank you."

"I had a fantastic buying experience with Jay and love my trailer. This is my 2nd Interstate trailer and was worth the drive to ensure I was purchasing a high-quality, locally-built trailer with sales and service readily available. I spent a large part of the weekend customizing the interior with hooks, cabinets, benches, and other items specific to my sledding and ATVing needs. I'll definitely recommend TrailersPlus and will be the place I look first should I need another trailer."
