Yes I have! We got a 12" dumping of snow Dec 9th. Worked pretty well! We've gotten about 4 dustings since... 2-3". Nothing worth plowing. I did however try it on my gravel driveway with 3", and it didn't work very well at all. I think what happened was that with a loose gravel base and not much snow the shoes get too much traction and actually force the top of the plow forward, and lifts the suspension a little. This caused only the front of the shoes to be in contact with the driveway. I plan to make pipe edges, but waiting on a friend to get the pipe. In the mean time, we're scheduled to get another storm this friday, so I think I'll modify the shoes tomorrow to lift the front a little. Maybe an inch.
Not sure about the push plates. They're the minute mount II. I do like that your truck mounts come off easier. I plan to take mine off in the spring, but I'll have to unbolt them.
