The Doepker RockR Tandem Lead is the compact side dump for operators who need a manoeuvrable lead trailer without stepping down in build quality. Its 16-foot Hardox 450 tub carries approximately 15.7 cubic yards, and with two retention pins removed the operator selects driver-side or curb-side discharge without repositioning. A Holland sliding lower fifth wheel with 24-inch slide lets the operator dial in weight distribution precisely, and it pairs with Doepker Tridem Single and SG end dumps for reverse B-train configurations.
