Buy or hire the TA5 if...
- you want one that is 185kg lighter empty
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.
