NQR Advantages Over Ford F-550 Super Duty:
- Longer maximum CA and CE dimensions on longest wheelbase allows NQR to handle longer bodies (20 ft. vs. 16 ft.)
- Higher payload when comparably equipped (more than a half-ton (1000 lb.) greater payload than F-550 for diesel models)
- Higher standard front GAWR contributes to durability (6830 lb. vs. 4800 lb. for gas engine models)
- Higher capacity rear axle contributes to durability (14,550 lb. vs. 13, 500 lb.)
- Tighter turning diameter (curb-to-curb) for comparable cab-to-axle ratio results in much better maneuverability and time saved on the job site (45.3 ft./120-in. CA vs. 57.9 ft./120-in. CA)
- Large, retractable West Coaststyle mirrors add to driver vision and safety (small, foldaway camper-style mirrors on F-550 Super Duty)
- Wider door opening for easy entry and exit (85 degree vs. 60 degree)
- Battery box on frame rails of NQR helps extend battery life by removing batteries from hot under-hood area, used by Ford
- Standard tilt and telescopic steering column contributes to driver comfort (optional tilt steering wheel on F-550 Super Duty)
- Tilt cab allows easy engine access, for reduced service and maintenance cost and downtime (limited engine access through hood on F-550 Super Duty)
- Greater visibility with larger windshield, larger side windows, larger side mirrors and lower dash, for driver vision and safety (Front sight line to ground is significantly shorter: 8.6 ft. for NQR vs. 23.8 ft. for Ford F-550 Super Duty)
- Higher frame yield strength contributes to durability (44,000 psi vs. 36,000 psi)
- 6-speed Aisin automatic transmission vs. 5-speed Ford automatic
- Fold-down passenger's seat and fold-down center seat with tray is standard, for convenience (not available on F-550 Super Duty)
- Standard exhaust brake contributes to braking power and brake component life (not available on F-550 Super Duty)
- Diesel engine is standard, for greater value at base price (optional on F-550 Super Duty)
- Longer diesel engine warranty helps manage repair costs (3 years/unlimited miles vs. 3 years/36,000 miles)
- Standard daytime running lamps contribute to safety (Optional on F-550 Super Duty)
