The Sterling All-Terrain was designed, tested and manufactured to the highest standards. Weighs just 35 pounds, yet pulls up to four tons. Steel and stainless steel at every critical point ensure superior strength and structural integrity. An eggshell design, unique to the Sterling All-Terrain and the Nighthawk distributes pressure throughout the tow bar, making them the world's strongest aluminum tow bars. The Sterling All-Terrain is easy to connect, and its solid 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 tow bar in its stored position. The Sterling All-Terrain comes complete with safety cables and power cord. Both are routed through a channel for added safety, convenience and a clean, uncluttered appearance. Beyond its many performance features, the Sterling All-Terrain is aesthetically pleasing — its stainless steel, metal-flake, powder-coated finish and sleek design complement your motorhome and your towed vehicle.
