Buy or hire the Portax L K if...
- you want one that is rated 2.2 tonnes heavier gross
- you want one that carries 1,078kg more
The longer 'L' version of the Portax K, giving taller or bigger horses more room while keeping the front-exit layout. It appeals to owners of warmbloods or cobs who found the standard Portax K too tight.

Buy or hire the PM310 if...
A lightweight option for owners of smaller motorcycles or scooters who want the least weight to tow. The 200 x 112cm bed suits scooters, trail bikes and smaller road bikes, and the 60kg unladen weight barely registers on a tow car.
