Cruisemaster DO35 Coupling with Handbrake

As caravans get heavier and more Australians use weight distribution systems, we went back to the drawing board to engineer a coupling that can handle it all.

Crafted from forged steel, laser-cut stainless steel, precision cast components, and premium polyurethane, the DO35v3 delivers uncompromising strength while reducing overall weight. In fact, it’s over 50% stronger than the previous model. The new design also eliminates the need for hitch adaptors*, so you can hit the road faster and with fewer hassles.

After a grueling RAT Run to Cape York, the DO35v3 proved its durability across some of Australia’s toughest terrain — all while retaining the simple drop-on attachment system trusted by travellers nationwide.
*Tested on HR Classic, HR Standard, Milford, and EZ-Lift systems.
