Specification works as a system
Axle ratings, suspension, engine torque, transmission, gearing, cooling, wheelbase, frame and fifth-wheel position must be assessed together for the intended trailer and operating conditions.

- Multi-axle and lift-axle configuration
- Rear ratio and low-speed performance
