I just purchased an older international with a chip box and a knuckle boom. The boom is a haib but its pretty warn out. Kinda loose and floppy with a couple leaks. But otherwise functional lol. The deal included another boom which is like new condition. Its an Effer 6000 az 25. I'm having trouble finding specs on this boom. Do any of you have experience with this model? I'm interested in the range and lift capacity. Thanks
