Lifecycle architectures for rental fleets couple pricing, vehicle assignment, maintenance scheduling and disposal timing, and the profit they add over revenue-based scoring has two sources that behave differently. Mileage steering changes the odometer reading at which a vehicle reaches disposal, and decision-focused forecast training reduces ranking regret at that point. Both sources matter only where the cost-optimal disposal mileage lies within a band around an odometer mark at which wholesale prices drop. The band half-width equals the residual-value forecast error divided by the slope of the retention margin. On realized retirements of midsize sedans at one enterprise rental operator, 28.2% of vehicles fall inside the band. Coupling adds $206 to $228 per vehicle there and $7 to $13 elsewhere, differences indistinguishable from zero. Mileage steering supplies 60.7% of the premium and survives a step-aware forecaster; the decision-focused component falls from $67.60 to $8.20 once the forecaster learns the price drops. Richer telematics raise profit by $86 to $118 per vehicle in every cell, so architecture and data are separable contributions. Operators can restrict the cost of coupling to vehicles inside the band.
