2 TRUCKS WERE AVAILABLE - 1 SOLD IMMEDIATELY! Challenger trucks were originally designed for the rugged west coast of Canada. Here they are shown as coal and log haulers working from sea level to 7000-foot elevations. These trucks are built tougher and heavier than normal multi-channel frame trucks to last 20 to 30 years in rugged off-highway jobs. With frames up to a minimum 30% tougher than other trucks in the same category they are usually limited in carrying capacity only by the number of axles and size of tires selected by the customer.
