The LM146 is a general-purpose flatbed aimed at landscaping, construction and plumbing trades that need a long, wide load bed with a high payload on a single 3500kg-braked chassis. It is used where loads are bulky or awkwardly shaped rather than plant machinery, which typically goes on the ramped GX range instead.

Buy or hire the ProLine Beavertail if...
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.
