Mammoth Overland
“Teardrop Trailers Reimagined”
About Mammoth Overland
Mammoth Overland is a Woodinville, Washington-based manufacturer of off-road travel trailers, built as a sister company to Vashon Aircraft, a light-sport aircraft manufacturer. Trailers are designed and built by Vashon's aerospace engineers using the same aircraft-grade materials and manufacturing techniques used to build Vashon's Ranger airplane. The company sells directly to customers rather than through a dealer network, and offers factory tours of its Woodinville shop by appointment. Its product line includes fully-equipped adventure trailers such as the HV, sold as a complete package rather than an a-la-carte build.
How they build
Mammoth Overland says it applies the precision and materials of aircraft manufacturing to off-road trailers, and states a commitment to building in the USA and to keeping trails and outdoor recreation clean, framing outdoor recreation as important to human health and happiness.
