Buy or hire the Portax L K if...
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 GD105 if...
- you want one that is rated 200kg heavier gross
The same market as the GD85 with about 60cm more bed length, which is the difference between fitting a load and not. Landscapers and anyone moving long materials or a quad choose it for the length rather than the payload, which is unchanged.
