Brian:
The mount seems fine. the weight does not seem to be problem.
The plow is a little slow in the down / up department, at approximately 1" per second, but not to bad.
The worst part is the slop in the angle. It seems that the blade can move 8 to 10 degrees left or right with the stock manual adjustment assembly. I really think that the power cylinders are required to hold it rigid side to side.
I'm still waiting to hear from Powerline on my inquiry about buying just the cylinders since we already have power hydraulics for the dump bed.
