“Seasonal adjustment takes dry van BL/BU to 8.3 months and  reefers to 10.7, so either way one looks at it, with or without seasonal  adjustment, this essentially commits the industry very deep into 2023,” McNealy  said. “Evidencing the concerns about supply-chain constraints, March’s build  per day declined 3% to 1,318 units per day, from February’s 1,359. That said,  overall build rose 14% m/m due to three more build days in March than February,  a 14% increase. Production growth continues its upswing, and our projections point  to a continuation of that trend.”
