Buy or hire the Race Box if...
- you want one that is rated 2.7 tonnes heavier gross
- you want one that carries 1,649kg more
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.

Near-identical to the PM310, rated for slightly heavier motorcycles up to 236kg. The two are the same trailer to look at, so the number to check before buying is the wet weight of the bike you intend to carry.
