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.

Buy or hire the HB511 if...
The wider step up from the HB506, for larger horses or owners who want more room in transit. The extra 12cm of internal width and 36cm of length cost 80kg unladen, which is worth checking against your tow vehicle before choosing it over the HB506.
