Against its class

Too few comparable declarations to rank this vehicle: a ranking needs five models from two makes, each behind at least ten declared vehicles.

Registered figures are counted over registrations; the register does not identify each vehicle's build, so they are not checked build by build. Drawn to the median registered figures. Lines are drawn only for recorded values. Where no source records a part — the cab, the front overhang, the spacing of the rear axles — it is drawn to a stated convention and is not dimensioned. A generic outline, not the manufacturer's design.

Comparable means: both vehicles record a form and an axle configuration, and they are the same; both figures are the same kind of figure, from the same market; engine power is within 20% of the lower of the two and gross weight within 25%. A model declared on the same mission, payload, vehicle group and reporting period comes first, then the closest power; at most six.
