Tom,
Thanks, the truck is pretty heavy and I have good counter weight in the crane so I think it will probably be able to dig with the boom level.
. The big problem I will probably have will be clearance for the crowd rope around the truck body, even swinging off the sides and rear. When I started mounting the slew ring I was not unhappy to let the crane ride entirely on top of the plastic gear because it give me another 1/4" of height to improve the clearance.
Now, to work on the drag bucket and thinking about how to power the truck.
Jim
