DO-35 V3 coupling

Drop-On 3.5Tonne Articulating All-Terrain Pin Coupling. 

*New* V3Plus Exclusive Features 

• Patented “Checklock” Gen.2 Dust Cap & Bumper for an easy, secure seal

• Improved Bumper molding gives the from reflector strip improved staying power

• Rear support webbing allows for mounting upside down on the underside of the drawbar

While the original concept for the DO35 was focused on off-road use we have found over the years that the DO35 has quickly become exceedingly popular on road vans as well; making it a great fit in all-terrains.

On Road Use

The inherit safety that comes with the articulation and ADR compliant locking mechanism of the DO35 means when the worst happens you couldn’t be in safer hands. If a roll over occurs when travelling, the DO35 is less likely to disconnect or roll the vehicle with the caravan/trailer than many other couplings currently available. (Effectiveness of coupling in this scenario will be affected by towing peripherals such as WDH systems).

Let’s not kid ourselves, you may start a trip with the best on intentions to keep to the flat top… But road conditions can change drastically and quickly! With the state of some “sealed” roads in Australia you may as well be on the dirt! The DO35 gives you the reassurance that your hitch can handle any road put in front of it.

Off-Road Use

When off-road articulation is king! The articulation of the DO35 allows you to take your caravan or trailer anywhere the 4wd can get with its rotational articulation both horizontally and vertically.

But it doesn’t end there… when we talk off-road in Australia, we are largely talking tough corrugations, this is where the build quality of the DO35 shines. Your coupling takes a beating on outback road, you will quickly find that only the toughest survive… the middle of nowhere isn’t the place to find this out! The DO35 has high quality poly bushes and is fully greaseable to reduce wear in the toughest of terrains.

Safety

The Cruisemaster DO35 V3 and V3Plus Range of couplings have been designed with safety as a priority! The positive locking 2 stage ADR compliant locking mechanism gives you the reassurance that the vehicle and caravan are truly secured. The patented “Checklock” Cap also doubles as both dust protection and a fool proof safety check, the cap will only fit onto the coupling when the lock is activated… if the cap doesn’t fit your not ready to tow!

Safety doesn’t end with the locking mechanism! Special consideration was given to the build materials of the DO35 V3 & V3Plus, it was increasingly important to have the added strength to manage the additional forces added by a Weight Distribution System while keeping the unit slimline and light weight.

This was achieved by a combination of a forged steel Yoke and Rear Nut for strength where it matters and a cast Housing to reduce weight were not safety critical.

We believe seeing is knowing; where others may be moving towards systems that enclose the safety critical locking components away from view we believe it is important to keep this components accessible and visible so you rest assured that a secure connection is achieved before travel.

Low Profile

The DO35 was designed with clearance in mind! Don’t let a grab handle or handbrake stop you from accessing your rear doors. The DO35 has been tested on many of Australia’s favorite touring vehicles to ensure adequate door clearance.

Fitment

The Cruisemaster DO35 uses what is considered the standard 4 bolt mounting pattern in Australia, meaning it’s really easy to upgrade from the standard ball or poly block couplings.

What towing accessories are essential for a caravan?

Essential towing accessories include towing mirrors, brake controllers, couplings, safety locks, and reversing cameras.

Why do I need extended towing mirrors?

Extended mirrors improve rear visibility when towing a wide caravan, helping reduce blind spots and improve safety.

What is a brake controller used for?

A brake controller activates and manages the caravan’s electric brakes in sync with the towing vehicle.

Are wireless brake controllers reliable?

Yes, modern wireless systems like Elecbrakes are widely used and provide consistent braking performance when installed correctly.

What is a DO-35 coupling?

A DO-35 is an off-road articulated coupling designed to allow greater movement and stability on uneven terrain.

Do I need a reversing camera for towing?

It is not mandatory, but it greatly improves visibility when reversing and parking a caravan.

What is sway control?

Sway control systems help stabilise the caravan and reduce side-to-side movement while towing.

Are towing mirrors required by law in New Zealand?

Yes, you must have clear rear visibility when towing, and extension mirrors are often required if the caravan blocks standard mirrors.

Can I install towing electronics myself?

Some items like mirrors and cameras are DIY-friendly, but brake controllers and sway systems are best professionally installed.

What is a stone guard used for?

A stone guard protects the front of the caravan from rocks and debris while towing.
