Gold Rush was founded in 1975 by Bill Schlott, a former drag racer and engineer. The first enclosed trailer was built in Bill's garage in response to the need for a protected trailer for his dragster, "Gold Rush," so named for the obvious reference to speed and quality, but also because Bill had always had an interest in the California Gold Rush.

Driven by his foresight and with trailer designs and engineering plans in his head, Bill pressed ahead with the production of enclosed aluminum trailers. The business gradually outgrew 2, 3 and 4 bay garages as word of mouth advertising fueled production for an expanding customer base, which eventually included racers of dragsters, motorcycles, and powerboats. As always, the emphasis was on innovation and quality. Gold Rush became a well-known name in the industry.
