Buy or hire the ProLine Beavertail if...
- you want one that has a bed 1cm longer
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.
