Just as Wally Byam wished, the company made nothing but improvements. Wally's experience in aircraft during the war led to the development of the dura-torque axle running gear. Its installation in the trailer eliminated 148 extraneous parts, absorbed bumps, and reduced slipping and side-sway. Additionally, it increased ground clearance by 8 inches and minimized the need to lubricate the axle assembly. Before 1957, the Clipper had 13 metal sections on either ends. In more recent designs, the sections were widened, reducing their number to just 7. By flattening the underside of the belly, Wally also reduced the Clipper's wind resistance. He also installed an 18 by 40 inch window at the back of the trailer in case the side door was jammed.
Throughout his career, Wally Byam scoured the world for new inventions and innovations that would improve the functionality and livability of the Airstream Clipper. Things as small as door hinges and as large as toilets, hot water heaters, and porcelain sinks were all on Wally's agenda. If Wally were still alive, much of his time would undoubtedly be spent in the aisles of Home Depot, searching for any small piece that might improve the Airstream. After a visit to Europe, Wally Byam found a heating system that provided radiant heat without taking up much space. He borrowed the idea to create his own heating system, which he later renamed the Byam Burner. In France, he found a compact refrigerator which replaced the inefficient ice-boxes that were once found in the early Clippers. Hot water systems and steam-pressured flush toilets are just a few of the other things that Wally brought to the Airstream over the years.
