As a bush aircraft a Fletcher would be one of the best, rough short strips, heavy loads, work all day, all week and all year back in the olden days. Mostly carrying more than it's empty weight. It has nose wheel. The undercarriage was less trouble, was better on rougher strips and cost less to maintain than the likes of a Beaver.
These days it's not considered a bush aircraft unless it has a tailwheel and flies in Alaska.
