When we started Carry-On, we began a journey that was about much more than a trailer. We wanted to meet the needs of your lifestyles, hobbies, projects and demanding jobs. Through innovation and a commitment to quality, we're now North America's number one selling trailer brand, but the journey's just begun.
The family owned United Trailer Factories was founded in Denmark in 1975 by brothers Niels and Jens Buhl and the company have produced the Variant brand of trailers ever since. The company, like its trailers, has grown in strength to become one of the largest quality trailer manufacturers in Europe with dealers in Denmark, Norway, Sweden, Germany, Italy, Austria, Belgium, and also with trailer manufacturing, and distribution in Australia, and in North America.
Founded in 1957 as an agricultural machinery dealership in southern Germany, Humbaur GmbH has grown into one of Europe’s leading trailer manufacturers.
Since producing its first trailers in 1984, the company has continually expanded its product range to include high-quality horse, livestock, utility, and specialty trailers.
With more than 1.2 million trailers produced, Humbaur is recognized for its commitment to innovation, precision engineering, and sustainable manufacturing.
