It is all aluminum , has a payload of 1600 lbs., and is amphibious. You have a choice of 35 hp diesel or 35 hp gas engine powering 4 independent hydraulic motors. We have designed it without rigid tracks so as to better climb over obstacles as well as traverse effortlessly through muddy or marshy terrain. There are no axles , chains or sprockets to malfunction unlike many of the similar vehicles on the market. We use 18" tracks turned by 4 ATV tires which adds to the ease of maintenance and performance .The 08' model has a carrying capacity of 4 standard. . The 09' model will have a propellor option for those longer treks through deeper water areas. The implementation of safari racks and cargo covers makes the Coona-Go the most versatile AAATV on the market. And because its only 6' wide by 10' long the size and portability of the unit makes it ideal for your next job or project. As soon as I can get speck sheets on the Coona-Go I will forward it to all thanks.
