Strengths and cautions
Works in its favour
- Rear-engine layout and 78-inch headroom
- B6.7 or L9 engine choices
- Large continuous passenger cabin
- High-capacity Type D chassis
Check before you buy
- Rear engine platform and cooling system require dedicated access
- Very large turning and parking footprint
- Higher purchase and component costs than Type C buses
- A full conversion can approach axle limits before GVWR is reached
