2027 Dragon 140BBL

Category classification, Trailer (vacuum). Tank capacity, 140 bbl vacuum configuration aimed at liquid and slurry work where volume matters more than deck space. New condition with zero miles points to clean internal surfaces and unused valves, making it a straightforward baseline for fleets that track contamination control and pump performance from day one. Running gear, suspension type, axle count, brake spec, and tire size are not provided, so those are the first items to verify before dispatch planning. Vacuum system details, pump make and model, CFM rating, relief valves, primary shutoff, and plumbing layout are also not listed, and they drive cycle time, safe recovery rates, and service intervals. Shell and fittings, inspect weld seams, manway lids, sight glasses, and all gasketed joints for uniform fit-up and proper torque marks. Kingpin plate, landing gear, and rear closure hardware should be checked for correct lubrication, smooth travel, and clean mounting points, with serial 1UNST4524VL213135 and stock 74137 used to tie inspection notes to the build paperwork.
