2027 Mack GR64F

Rolloff chassis spec points to heavy municipal and construction container work, short-cycle duty, and frequent PTO engagement. New condition with essentially delivery miles means the inspection focus is baseline setup, fastener torque checks, and verifying all body upfit interfaces before the first loaded cycles. Powertrain centers on a Mack MP8-415 paired with a Mack TMD13AFO HD 13-speed. Rear gearing at 3.79 with 20k front and 46k rears favors startability and controlled low-speed work over high-speed cruise, a sensible match for rolloff launches, yard maneuvering, and stop-and-go routes. Camelback suspension is a vocational choice, it carries point loads well and tolerates uneven surfaces, with the tradeoff of a firmer empty ride. Frame rails and upfit area deserve a close look for rolloff compatibility, including rail spacing, clearances at the back of cab, and any pre-drilled or reinforced sections intended for hoist subframe mounting. Wheelbase at 273 inches gives room for hoist and container length planning, while keeping turning radius manageable for tight drops. Cab layout as a daycab keeps weight and complexity down for local cycles. Data plates and identifiers are present, serial 1M2GR3GC4VM058498, stock O:26040121; ECM details were not provided, so engine hours and fault history would need to be pulled during a scan to confirm a clean baseline before service.
