Both (6×6) tractor units use the same cab design as those on Iviko McGirus off-road trucks, with the towing seat positioned above the rear axle. The only difference is that the 330-40ANWTM model uses a turbocharged diesel engine, while the 330-32ANWTM model uses a non-turbocharged diesel engine from the same base model.
Both vehicles can be equipped with either two 196kN (20000kgf) hydraulic winches or one simple 294kN (30000kgf) winch. Other optional equipment includes a cab roof window, an anti-aircraft lighting system, improved electrical systems allowing for wading depths up to 1.2m, and a two-compartment crew cab. For use in sandy terrain, the 330-40ANWTM model can be fitted with specialized sand tires: a single 14.00×20 tire at the front and a single 24×20.5 tire at the rear.
