Now, our best tow bar is even better — with non-binding All Terrain™ technology!

The Sterling All Terrain was designed, tested and manufactured to the highest standards…yours. And now, ROADMASTER’s best tow bar is even better — with non-binding All Terrain technology, you’ll never struggle to release your tow bar again.
The Sterling All Terrain weighs just 35 pounds, yet pulls up to three tons. Steel and stainless steel at every critical point 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 electrical wiring cord. Both are routed through center channel guides for added safety, convenience, and a clean, uncluttered appearance.
Beyond its many performance features, the Sterling All Terrain is aesthetically pleasing — its anodized 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.

There’s no more binding with an
All Terrain Freedom Latch™
Releasing your towed car is easy with ROADMASTER’s All Terrain Freedom Latch — even when the tow bar is at a hard angle, or the towed car is out of level. The Sterling All Terrain’s Freedom Latches disconnect first time, every time.
No other tow bar makes towing this simple!

   
  

A unique eggshell design distributes pressure throughout the tow bar, making the Sterling All Terrain the world’s strongest aluminum tow bar.
• Aircraft-grade aluminum, anodized for maximum durability
• Computer-designed and -tested for superior strength and styling
• Exceeds all competitive products in stress and fatigue testing

Computer tested
ROADMASTER uses computerized testing on every new tow bar design. The program is called “FEA,” which stands for “Finite Elemental Analysis.” If that sounds complicated, that’s because it is — FEA is the same program NASA scientists use to test their new designs.
FEA transforms two-dimensional design drawings into three-dimensional objects, which can be rotated and studied on the screen as thousands of pounds of force are applied. Stress in the steel is pinpointed, and the design is manipulated to remove it.
ROADMASTER is the only towing products manufacturer to use computerized testing — as well as “real world” physical testing — to ensure structural integrity, longevity, and the safety of your family.

Exclusive channel guides The safety cables and electrical wiring cord are both routed through the built-in channel guides. No need to wrap the cables or wiring around the arms of the tow bar!

Quick, convenient, secure... From stow to tow in seconds! Patented storage latch Simply fold the Sterling All Terrain toward the motorhome and the storage latch will “click,” automatically locking it in place. When you’re ready to tow, just press the storage latch to release the tow bar.       ‘EZ Hook’ safety cables Included with the Sterling All Terrain, ‘EZ Hook’ safety cables are faster to connect than other cables — at the towed vehicle, a stainless steel ball at the end of the cable latches into a slotted anchor plate. Heavy-duty, drop-forged steel hooks, with spring-loaded latches, connect the cables at the motorhome. Vinyl coating prevents the safety cables from scratching or chipping the tow bar.
