Two mistakes I would have warned against, but its not the end of the world!
1) Its too narrow for a full size truck.
2) It is kinda difficult to hitch up compared to the newer Smart Hitch's or even the RT-III's.
3) They raised the center pivot hinge on the newer models, and this allows a better flow of snow when side blading. Now, I am forced to take about a 1/2 swath when side blading. Any more of a "bite" and the snow on the leading blade half builds up at the hinge point, and ends up spilling over on me. The newer design places the hinge back more, and the edge is able to flow snow across better.
Here is my pic of my edge, and it leaves a 3" wide by 5/8" high strip of snow when I am angling to the side or in the V position.
