Positioned for classic car owners and smaller motorsport teams who want their car fully enclosed and weatherproof but do not need the wider bed of the Race Sport or Race Transporter ranges. The narrower internal width suits a single classic or compact race car rather than a modern GT car.

Buy or hire the TA5 if...
The standard British livestock trailer, and the one most smallholders and farmers picture when they say livestock trailer. Low loading height and flexible partitions matter more here than raw capacity, because the job is getting animals in and out calmly rather than maximising a payload.
