The Doepker Legacy is the lightest and strongest aluminum Super B grain trailer on the market, built around the Doepker-designed Uni-Link system that delivers structural strength never before seen on an aluminum trailer. Its exclusive one-piece aluminum double-wall slope uses minimal rivets and carries no horizontal seams, producing unmatched cleanout and maximum payload capacity. An industry-first open-end dual aluminum wall lets crews service the suspension and slope area from outside without any disassembly.
