Strengths and cautions
Works in its favour
- Rear engine moves noise and heat away from the driver
- B6.7 and L9 power options
- Flat front and large-capacity body
- Good candidate for highway-oriented full-time builds
Check before you buy
- Rear engine deck and access hatches limit bedroom design
- Cooling-system condition is critical
- Long rear overhang and departure angle must be checked
- The largest engine does not guarantee ideal highway gearing
