Maintenance cost projections for the box trucks for sale are based on real-world fleet data and manufacturer service schedules. Electric models like the Futian Auman incur an average annual maintenance cost of $650-$800 over a 5-year period, primarily for battery health checks (every 20,000 km), brake pad replacements (every 40,000 km), and coolant system flushes (every 60,000 km). The electric drivetrain eliminates engine oil changes, reducing maintenance labor by 35% compared to diesel counterparts. Diesel-powered box trucks, with a 4.5L engine, have an average annual cost of $1,500-$1,800, including: 1) oil changes (every 10,000 km, $120), 2) fuel filter replacements (every 20,000 km, $85), 3) timing belt service (every 100,000 km, $650). Preventive maintenance packages—including 24/7 roadside assistance, priority service scheduling, and genuine OEM parts—can reduce costs by 15-20%. Our service department offers customized maintenance plans based on mileage, cargo type, and operating environment, with detailed cost breakdowns (labor, parts, diagnostics) and service reminders integrated into fleet management systems.
