Buy or hire the GD85 if...
The entry point of the Ifor Williams general duty range and one of the most common working trailers in Britain. Smallholders, gardeners and tradespeople buy it for everyday hauling without needing a heavy tow vehicle, and the twin-axle version roughly doubles the payload for a modest gain in unladen weight.

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.
