Mine's a RVM rock bucket with dual grapple tops. Had to reroute the hoses as they were poorly placed and not protected. I've torn off 6ish hoses in the year I've owned it. Then one cylinder mounting ripped out. I think the problem was that they are mounting grapples as an option on the rock buckets and do not use heavy enough square tubing.
In it's defense, I paid $1500 for it and I've abused the hell out of it... I like that it's built extra deep - you could grpple a 4 by 8 sheet of plywood with it. It isn't very handy for raking up sticks.
