The Doepker King B Logger is a full B-train configuration built for demanding long-haul forestry operations, with lead and rear trailers each engineered to run a Holland fifth wheel, weld-in king pins and heavy-duty telescopic bolt-on dolly legs. A 60" tridem lead and 60" tandem rear — with an optional tridem rear for maximum payload — sit on air ride with dump valve and pressure gauge and 2S2M ABS on both units. Five-tier StrongArm bunk and stake packages with patented reversible four-bar wrap winches make it the most capable logger in the Doepker lineup.
