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 four 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.

• Telescoping, independently-adjustable inner arms are easy to maneuver into position. Simply pin them in place and then drive your motorhome away and the arms automatically center and lock in place.

• The largest hook-up radius in the industry means you don’t waste time lining up your towed vehicle. You can’t say this about many things in life but connecting the Sterling All-Terrain is just like horseshoes — “close” is good enough!

• Self-lubricating polyurethane bushings eliminate friction between the inner and outer arms for smooth, easy operation. Other tow bars have steel riding on steel.

• Locking 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 lift the tow bar up and press the storage latch to release the lock.

• Channel guides
The safety cables and power cord are both routed through the built-in channel guides for protection against damage or dragging, and for a clean, uncluttered look. There’s no need to wrap the cables or the power cord around the tow bar every morning.

• Motorhome-mounted
When you reach your destination, the Sterling All-Terrain conveniently stores out of the way on the back of the motorhome.

• No ball mount to drag
The Sterling All-Terrain mounts into a 2-inch receiver.

• Solid stainless steel inner arms
Solid stainless steel inner arms for smooth, trouble-free operation and easy maintenance. Stainless steel looks better, lasts longer and prevents corrosion that binds — ROADMASTER tow bars are the most rust-free in the industry.

• A lustrous, high-tech powder coat finish for maximum durability. This finish exceeds all 500-hour salt spray, high-impact and extreme weather standards. In this process, charged particles of pigment are sprayed onto the surface of the tow bar, then baked at more than 400 degrees. The paint fuses to the metal. The result is a uniform, thick and extremely durable finish — three times stronger than solvent-based paint.

The cam design inside the Freedom Latch transforms linear motion into rotary motion at a 400-to-1 ratio — five pounds of force against the latch equals 2,000 pounds of force against the lock. So you’ll never have to straighten and align your towed vehicle and motorhome to release the tow bar — the Freedom Latch releases the tow bar at any angle or bind — first time, every time. No other tow bar manufacturer makes towing this simple.

• Strength, in spades
A unique eggshell design distributes pressure throughout the tow bar, making the Sterling All-Terrain the world's strongest aluminum tow bar.

• Includes safety cables and power cord
• 6- to 7-wire power cord with one 6-wire plug (attached), one 7-wire plug and the 6-wire electrical socket
• Safety cables — for quick connect and disconnect — “easy on, easy off!”

• Heavy-duty, drop-forged steel hooks with spring-loaded latches connect the cables at the motorhome. A vinyl coating prevents the cables from scratching or chipping the tow bar.
