The Doepker Classic Tandem Steel 2 Hopper puts the same open-end bulker design that changed the industry in 1997 onto a tandem axle group, in 36' or 40' lengths. Two 14-gauge steel hoppers with rack & pinion chutes sit under 16-gauge steel walls with 4" vertical corrugations and straight ends, with tare weights starting around 9,600 lbs to keep payload where it counts. It is the size that fits farm yards, bin sites and shorter approaches without giving up Doepker's zinc, Duraguard and heat-cured finish system.
