About Us

Castleton’s roots go back to the early 60’s when a 3 ton truck and 100 bushel box was considered state of the art. After building custom grain boxes our founder decided to take the big step and started Castleton in 1993 with a vision to supply the customer with a trailer that would be durable and affordable.

For over 23 years we have been refining this vision through listening to our customers, innovative design, and world class materials. In 1999 Castleton created our gravel belly dump trailers due to strong demand and in 2009 we acquired Superior Forestry Trailers to better serve our ever growing customer base.

We understand that building trailers for the diverse and often harsh climate our country has is challenging. Our trailers are built to withstand the ever changing, harsh climates. We strive to use the best materials available in our business to create a long lasting, lighter weight trailer.

Our vision still has not changed and we are still as enthused about trailers as the day our first trailer rolled off the assembly line. Take a tour of our site and see the Advantage of joining the Castleton-Superior family.
