The Bowlus Road Chief was the original riveted aluminum travel trailer, it was developed by Hawley Bowlus in 1934 and then famously emulated by Airstream two years later in 1936.

Hawley Bowlus And The Bowlus Road Chief

Bowlus was the Superintendent of Construction on Charles Lindbergh’s aircraft, the Spirit of St. Louis. He was also a globally renowned glider designer and pilot before he ever turned his attention to travel trailers.

Hawley Bowlus noted the growing popularity of travel trailers in the late 1920s and 1930s, he realised he was uniquely placed to solve their single biggest drawback – weight. Many travel trailers had steel chassis and frames with heavy wooden bodies, as a result they severely taxed the relatively low horsepower cars of the era when towed.

Bowlus turned his experience in aircraft design and construction to the world of travel trailers. He developed a trailer that was essentially a state-of-the-art aircraft fuselage on wheels, with a semi-monocoque riveted aluminum body that was specifically designed to be as aerodynamic as possible.

The first Bowlus travel trailer weighed just 1,100 lbs, it was a revelation that would transform the fledgling industry and directly lead to the lightweight trailers we see today with designs developed with aerodynamics in mind.

Sadly Bowlus travel trailers wouldn’t survive the Great Depression, but Airstream did, and so the idea of riveted aluminum travel trailers lived on.

In more recent years Bowlus has been brought back into full production, with trailers that strictly adhere to Bowlus’ original vision, but with luxurious interiors that are fully appointed with modern amenities.
