The largest Ifor Williams tipper. A 3.6m by 1.95m body is chosen for bulky, lighter loads - green waste, clearance and bark - where volume runs out before weight does, and it is a staple of plant and tool hire fleets. Formerly sold as the TT126.

The ProLine Beavertail suits owners of low-ground-clearance cars, since its beavertail ramp lets a car drive on and off without grounding, unlike a flat-bed transporter. PRG offers it across twin and tri-axle chassis so buyers can match the trailer to a 3000kg or 3500kg tow limit.
