Proudly designed, developed and built right here in Australia.

The R.A.S.V. Medium – Heavy Duty, Tactical Flat Deck Trailer can be configured for almost any application with a variety of load handling capabilities to specifically match your requirements.

100% Australian made.



The main design feature of the M-H CS 4.7’s trailer frame is the 125 x 75 x 4mm Box Section chassis that runs the full length of the trailer .
The hot dipped galvanised chassis is made of Laser Cut, CNC folded Componants with open chassis members allowing for easy wash down and cleaning, with no enclosed areas where mud, sand and salt can get trapped and cause corrosion.


Above the main chassis you will find another secondary chassis sub frame. The upper section of the trailer is made of a combination of Aluminium and steel components. Reducing over all weight and adding strength where it is needed most. Siting above the main steel chassis rails we have introduced two 150 x 50 x 5mm Aluminium C section chassis rails. In combination with 16 – 70 x 30 x 30 x 4mm Z profile Decking cross members at 200mm Centers.

All cross members are individually attached to the lower aluminium chassis sub frame with 4 – 6.5mm 1500 kg sheer rated structural rivets. The decking side rails are made from 5mm Zinc Plated Steel with integrated ratchet tie down points incorporated into the side rail design. The top deck can also be fitted with a variety of different load restraint tie down points as requested.

Depending on customer load and weight requirements the decking plates can also be optioned to either 3mm galvanised steel checker plate or 4mm Aluminium plate. Trailers also have the option to be fitted with a removable Front Head Board, 187 Ltr draw bar mounted Aluminium Tool Box, Side under tray storage boxes, Maxtrax Recovery mounts and an Axe, Shovel and Mattock mount.


The M-H CS 4.7’s suspension is built for a lifetime of Heavy Duty Off Road use with ability to incorporate interchangeable key suspension components allowing the trailer to be upgraded as your needs change. The base model is fitted standard with a coil spring/drum brake configuration with the option of upgrading spring rates and disc brake variants at any time in the suspensions life cycle.

Land Force Defence Off Road Suspension.

Incorporating Land Force Defences heavy duty military suspension means that you are less likely to run into problems out in the field. A sturdy 63mm stub axle, extra-large 3.3T VC bearing combination, premium monotube dampers and lockable toe and camber adjusters means you can spend more time operating in remote areas and less time dealing with overheated components and maintenance problems. Both front and rear suspension assemblies have been mounted to modular frames independent to each other. Allowing for full or partial suspension assembly replacement in the field.
