Rugged Aluminum Frame

Our aluminum trailers are built to last, starting with rugged main tubes and fully welded joints. We know what types of roads our trailers are dragged over when they leave our facility and our trailers are ready for them.

Quality Trailer Parts

A strong frame is only as good as the components to support it. This is why we use only the best of parts on our aluminum trailers like galvanized Dexter torsion axles, high quality radial tires, LED lighting, and self-adjusting brakes.

2.5x Stronger Roof

Our roofs are built with rugged 1″×2″ aluminum tubes on 16″ centers. That means a roof nearly 2.5 times stronger than many other trailers on the market. We tend to get a lot of snow in New Hampshire, our trailers are ready for it.

Attention To Detail

Every trailer we build is checked and double checked before it leaves our shop. We want to make sure our trailers are looking their best with screws lining up, lines cut straight, doors installed tight, and every trim screw properly located.
