Forward Reconnaissance Support Trailer. (Coil Spring Variant)

This 100% Australian made Off Road Trailer is proudly designed, developed and built right here in Brisbane Australia.
Fashioned after our R.A.S.V. Tandem. (Remote Area Support Vehicle) The CS 4.1 is a lighter more compact, single axle, coil sprung, off road trailer with all the same features and functionality as it’s larger cousin.

Each of our aluminium trailer bodies come fully powder coated or painted inside and out with a corrosion resistant galvanised or painted steel Chassis.

The fully monocoque constructed bodies are made from high grade 2.5mm laser cut and CNC formed aluminium plate. All of our aluminium components are assembled with 6.4 mm structural rivets and incorporate strategically welded joints through out the design for extra strength.

The monocoque body is made up of 7 individual aluminium storage compartments. Which are all interconnected by internal ventilation openings to allow for even air pressurisation through out the entire body. The positive air pressurisation is achieved with the use of an external air pressurisation system with serviceable air filters. Keeping the entire trailer free from dust on even the toughest off road environments.
