The older MAX had some issues. They have had a hard time living down the bad press. They have improved most of the issues. The solid axles, O-ring chain, splined axles, double bearings on the axles, and front bearing guards have taken care of the major issues. Up North ,the throttle cable heater is a must, to keep it from freezing up. The MAX can also be fitted with tracks. The down side is that you have to have two sets of tires. A smaller set to allow clearance for the tracks and a taller set when running without the tracks. The Route 6x6 site is wealth of info.
