Diamond C Trailers

Diamond C Trailers is a family owned and operated manufacturer of open steel trailers based in Mt. Pleasant, Texas, and has been building trailers since 1985. The company states that it aims to produce innovative, feature-rich trailers as a way of promoting the well-being, growth and success of its team members, customers and communities. Open steel trailers of this kind are typically towed by pickup trucks and are a common workhorse for contractors, farmers and owner-operators who need to move equipment and materials between sites.

Its lineup spans utility trailers, car haulers, dump trailers, heavy duty equipment and tilt trailers, flatbed gooseneck models, pintle hitch trailers and step deck trailers. Featured models include the LPT low profile dump trailer with telescopic cylinder technology, the FMAX gooseneck built on an engineered beam, and the LPX low profile equipment trailer. The range is organised around use types such as agriculture, construction, hotshot hauling, landscaping and recreational weekend use, which reflects how trailer buyers typically shop by job rather than by chassis specification. The company describes its niche as extraordinary trailers with service to match.

Diamond C sells through a network of more than 100 dealer partners across the U.S. and Canada, and offers an online build-and-price configurator, a parts department and financing options through Sheffield Financial and Synchrony Bank. A dealer model is common in the trailer industry, letting buyers inspect units and arrange service locally.

The business was started by an East Texas couple after a local trailer manufacturer closed, leaving customers without product and workers without jobs. The company says it operates on traditional family values of honesty, respect, humbleness and integrity, and its tagline "Do Work. Love Strong." refers back to those origins.
