The Sterling All-Terrain was designed, tested and manufactured to the highest standards. The Sterling All-Terrain weighs just 35 Pounds, yet pulls up to three tons. A unique eggshell design distributes pressure throughout the tow bar, making the Sterling All-Terrain the world's strongest aluminum tow bar with steel and stainless steel at every critical point to further ensure superior strength and structural integrity. The Sterling All-Terrain is easy to connect, and its stainless steel inner arms telescope, center and automatically lock as you pull away. Once you've reached your destination, a unique storage lock secures the Sterling All-Terrain in its stored position. The Sterling All-Terrain comes complete with safety cables and power cord. Both are routed through a center channel for added safety, convenience and a clean, uncluttered appearance. Beyond its many performance features, the Sterling All-Terrain is aesthetically pleasing, its powder-coated finish and sleek design complement your coach and your car. As well they should — the Sterling All-Terrain exemplifies ROADMASTER’s highest standards, as well as yours.
