Buy or hire the AT 4019/27 if...
A tipping, low-bed car transporter from German builder Bockmann, rated to carry a car or light plant up to around 2 tonnes. The tipping bed and integral winch let one person load a non-runner without a separate ramp, which is what puts it in vehicle recovery and plant fleets rather than ordinary car trailers.

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.
