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.
