Buy or hire the GD105 if...
- you want one that is rated 300kg 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.
